Its simplicity and small size make it a high efﬁ ciency alternative to charge pump designs. It is designed to start up from a single alkaline or nickel cell, with input voltages as low as 1V, or from two or three cells (or a Li-ion battery), with voltages as high as 4.5V. Once started, V IN can be as low as 0.5V (depending on load current) and maintain regulation. The output voltage is preset internally to either 3V, 3.3V or 5V. Peak switch current is 400mA minimum, providing regulation with load currents up to 150mA, depending on input voltage. Synchronous rectiﬁ cation provides high efﬁ ciency opera-tion while eliminating the need for an external Schottky diode. True output disconnect eliminates inrush current at start-up, and allows V OUT to be disconnected from V IN, for zero shutdown current.The output disconnect feature also allows the LTC3525 to maintain regulation with an input voltage equal to or greater than V OUT. Note, however, that the synchronous rectiﬁ er is not enabled in this mode resulting in lower ef-ﬁ ciency and reduced output current capability.The operating quiescent current is only 7µA typical, allow-ing the converter to maintain high efﬁ ciency at extremely light loads.ShutdownThe LTC3525 is shut down by pulling S H D N below 0.4V, and made active by raising it above 1V. Note that S H D N can be driven as high as 6V, however, if it is more than 0.9V above the higher of V IN or V OUT, the S H D N input current will increase from zero to 1.5µA.After the S H D N pin rises, there is a short delay before switching starts. The delay is 20µs to 120µs, depending on input voltage (see Typical Performance Characteristics curve).Start-upA start-up oscillator allows the LTC3525 to start with input voltages as low as 1V. It remains in start-up mode until two conditions are met. V OUT must exceed V IN by at least0.2V typical and either V IN or V OUT must be greater than1.8V typical.During startup, the synchronous rectiﬁ er is not enabled, and the internal P-channel synchronous rectiﬁ er acts as a follower, causing the peak voltage on SW to reach (V IN + 1V) typical. This limits inrush current by maintaining control of the inductor current when V OUT is less than V IN. To reduce power dissipation in the P-channel synchronous rectiﬁ er when the output is shorted, a foldback feature is incorporated that reduces the peak inductor current when V IN is more than 1.7V greater than V OUT.Normal OperationOnce V OUT has increased more than 0.2V typical above V IN, and either voltage is above 1.8V, normal operation begins, with synchronous rectiﬁcation enabled. In this mode, the internal N-channel MOSFET connected be-tween SW and GND stays on until the inductor current reaches a maximum peak value, after which it is turned off and the P-channel synchronous rectiﬁ er is turned on. It stays on, delivering current to the output, until the inductor current has dropped below a minimum value at which point it turns off and the cycle repeats. When the output voltage reaches its regulated value both switches are turned off and the LTC3525 goes to sleep, during which time the output capacitor supplies current to the load. Once the output voltage drops approximately 9mV below the regulation value the IC leaves sleep mode and switching is resumed.The LTC3525 has been designed for low output voltage ripple. The output voltage ripple is typically only 20mV peak-to-peak at light load and 60mV peak-to-peak at83525fa93525faOPERATIOfull load using the minimum recommended 10µF output capacitor for the LTC3525-3.3 and a 22µF capacitor for the LTC3525-5 (due to the capacitor’s DC bias effect). An antiring circuit damps any oscillation at the switch node when the inductor current falls to zero.Power Adjust FeatureThe LTC3525 incorporates a feature that maximizes efﬁ ciency at light load while providing increased power capability at heavy load by adjusting the peak and valley of the inductor current as a function of load. Lowering the peak inductor current to 150mA at light load optimizes efﬁ ciency by reducing conduction losses in the internal MOSFET switches. As the load increases, the peak inductor current is automatically increased to a maximum of 400mA. At intermediate loads, the peak inductor current may vary from 150mA to 400mA. Figure 1 shows an example of how the inductor current changes as the load increases. Please note that output capacitor values greater than 47µF will result in higher peak currents than necessary at light load. This will lower the light load efﬁ ciency.The valley of the inductor current is automatically adjustedas well, to maintain a relatively constant inductor ripplecurrent. This keeps the switching frequency relatively constant.The maximum average load current that can be supported is given by:I V V Amps O MAX IN O()=03.••ηWhere η is the efﬁ ciency (see Typical Performance Char-acteristics).The “burst” frequency (how often the LTC3525 delivers a burst of current pulses to the load) is determined by the internal hysteresis (output voltage ripple), the load current and the amount of output capacitance. All Burst Mode operation or hysteretic converters will enter the audible frequency range when the load is light enough. However, due to the low peak inductor current at light load, circuits using the LTC3525 do not typically generate any audible noise.3525 F01INDUCTOR CURRENT 100mA/DIVLOAD CURRENT 50mA/DIV10µs/DIVFigure 1.

A direct pin-for-pin replacement for the earlier device, it combines advanced processing techniques and circuit design to provide improved reference accuracy/ and extended common mode range at the error amplifier and current limit inputs. A DC-coupled flip-flop eliminates triggering and glitch problems, and a PWM data latch prevents edge oscillations. The circuit incorporates true digital shutdown for high speed response, while an undervoltage lockout circuit prevents spurious outputs when the supply voltage is too low for stable operation. Full double-pulse suppression logic insures alternating output pulses when the shutdown pin is used for pulse-by-pulse current limiting.BLOCK DIAGRAMV INInput Voltage Collector VoltageError Amp Common Mode RangeCurrent Limit Sense Common Mode Range Output Current(each transistor)Reference Load Current Oscillator Charging Current Oscillator Frequency RangeR T Oscillator Timing Resistor C TOscillator Timing CapacitorOperating Ambient Temperature RangeIP1524B IP2524B IP3524BNOTES1.Test Conditions unless otherwise stated:V IN = 20V , I REF = 0.T J = –55 to +125°C for IP1524B T J = –25 to +85°C for IP2524BT J = 0 to +70°Cfor IP3524B 2.R T = 2.7K Ω, C T = 0.01µF unless otherwise stated.LAB4.35.26.50.10.30.67104.90 5.005.104.855.151155254075257012013943470.1112801404007003.04.00.40.5 1.23.7 4.00.61 1.1-12101100.114.35.26.50.10.30.67104.955.005.054.905.10110515407525701201104143450.1112801404007003.0 4.00.40.5 1.23.7 4.00.61 1.1-10.15150.11IP1524B IP2524B IP3524BParameterTest Conditions1Min.Typ.Max.Min.Typ.Max.UnitsV IN Undervoltage Threshold Turn–on Hysteresis Operating CurrentOutput Voltage Line Regulation Load Regulation Temperature Stability Short Circuit Current Long Term StabilityInitial Accuracy Voltage Stability Temperature Stability Minimum Frequency Maximum Frequency Clock Amplitude Clock Pulse Width Sawtooth Peak Voltage Sawtooth Valley Voltage Sawtooth Valley T.C.Input Offset Voltage Input Bias Current Input Offset CurrentV IN Rising V IN = 7 to 40VT J = 25°C V IN = 7 to 40V I L = 0 to 20mAV IN = 7 to 40V I L = 0 to 20mAV REF = 0T J = 25°CT J = 25°C V IN = 7 to 40VR T = 150k ΩC T = 0.1µF R T = 2k ΩC T = 470pF Output, Pin 3C T = 0.01µF Output, Pin 3C T = 0.01µFC T = 0.01µF C T = 0.01µF T J = 25°C V CM = 2.3 to V REF V CM = 2.3 to V REF V CM = 2.3 to V REFV mAVmV mA mVkhrkHz %Hz kHz Vµs V mV/°CmV µAELECTRICAL CHARACTERISTICS (T J = Over Operating Temperature Range unless otherwise stated)ERROR AMP SECTIONOSCILLATOR SECTION2REFERENCE SECTIONTURN–ON CHARACTERISTICSIP1524B IP2524B IP3524BParameterTest Conditions1Min.Typ.Max.Min.Typ.Max.Units60757090761200.20.53.84.2124549180200220-1-102.00.110.6500.1200.20.41.0 2.2171916.5180.20.160757090761200.20.53.84.2124549180200220-1-102.00.110.6500.1200.20.41.0 2.2171916.5180.20.40.10.2DC Open Loop Gain Common Mode Rejection Supply Voltage Rejection Output Low Level Output High Level Gain Bandwidth Product Minimum Duty Cycle Maximum Duty CycleSense Voltage Input Bias CurrentHigh Input Voltage High Input Current Low Input Voltage Shutdown DelayCollector Leakage Current Collector Saturation Voltage Emitter Output Voltage Emitter Voltage Rise Time Collector Voltage Fall Time∆V O = 1 to 3V R L ≥10M ΩV CM = 2.3 to V REFV IN = 7 to 40V I SINK = 100µA I SOURCE = 100µA T J = 25°CV PIN1– V PIN2≥150mV V PIN2– V PIN1≥150mVV CM = 0 to 17.5V V IN = 7 to 40V V CM = 0 to 17.5V V IN = 7 to 40VV SHUTDOWN = 5VPin 10 to output T J = 25°CV CE = 60V I C = 20mA I C = 200mA I E = 50mA I E = 200mA R E = 2k ΩT J = 25°C R C = 2k ΩT J = 25°CdBV MHz%mV µAV mA V ns µA V V µsLABPWM COMPARATORERROR AMP SECTION (cont.)CURRENT LIMIT AMPLIFIERSHUTDOWN INPUTOUTPUT SECTION (each transistor)NOTES1.Test Conditions unless otherwise stated:V IN = 20V , I REF = 0.T J = –55 to +125°C for IP1524B T J = –25 to +85°C for IP2524BT J = 0 to +70°Cfor IP3524B ELECTRICAL CHARACTERISTICS (T J = Over Operating Temperature Range unless otherwise stated)LABAPPLICATIONS INFORMATION854OUTSENSE+C.L.–C.L.GND100ΩRAW SUPPLY RETURNRETURN+V R SENSEOUT+C.L.–C.L.RETURNRAW SUPPLYC C R +V 135412A B11+C.L.–C.L.E BE A1445SENSER 3163.2k ΩTTL3163.2k ΩCMOS1N9142N23691112+15VD1Q11.6k ΩTO LOAD1112Q14.7k Ω1.6k Ω0.01µFQ2TO LOADCurrent Sensing in the Ground LineSensing Primary Current with an Emitter ResistorDriving Power MOSFETsCurrent Sensing in the Output LineOscillator Sync to an External ClockA.
