The feedbackthreshold voltage is 0.6V.MP2105 – 1MHz 800mA SYNCHRONOUS STEP-DOWN CONVERTERTMOPERATIONThe MP2105 is a constant frequency current mode PWM step-down converter. The MP2105 is optimized for low voltage, Li-Ion battery powered applications where high efficiency and small size are critical. The MP2105 uses an external resistor divider to set the output voltage from 0.6V to 6V. The device integrates both a main switch and a synchronous rectifier, which provides high efficiency and eliminatesan external Schottky diode. The MP2105 can achieve 100% duty cycle. The duty cycle D of a step-down converter is defined as:%100V V %100f T D INOUTOSC ON ×≈××= where T ON is the main switch on time, and f OSC is the oscillator frequency (1MHz).INENFBGNDSWMP2105_BD01Figure 1—Functional Block DiagramMP2105 – 1MHz 800mA SYNCHRONOUS STEP-DOWN CONVERTERTMCurrent Mode PWM ControlSlope compensated current mode PWM control provides stable switching and cycle-by-cycle current limit for superior load and line response and protection of the internal main switch and synchronous rectifier. The MP2105 switches at a constant frequency (1MHz) and regulates the output voltage. During each cycle the PWM comparator modulates the power transferred to the load by changing the inductor peak current based on the feedback error voltage. During normal operation, the main switch is turned on for a certain time to ramp the inductor current at each rising edge of the internal oscillator, and switched off when the peak inductor current is above the error voltage. When the main switch is off, the synchronous rectifier will be turned on immediately and stay on until either the next cycle starts. Dropout OperationThe MP2105 allows the main switch to remain on for more than one switching cycle and increases the duty cycle while the input voltage is dropping close to the output voltage. When the duty cycle reaches 100%, the main switch is held on continuously to deliver current to the output up tothe PFET current limit. The output voltage then is the input voltage minus the voltage drop across the main switch and the inductor.Short Circuit ProtectionThe MP2105 has short circuit protection. When the output is shorted to ground, the oscillator frequency is reduced to prevent the inductor current from increasing beyond the PFET current limit. The PFET current limit is also reduced to lower the short circuit current. The frequency and current limit will return to the normal values once the short circuit condition is removed and the feedback voltage reaches 0.6V.Maximum Load CurrentThe MP2105 can operate down to 2.5V input voltage; however the maximum load current decreases at lower input due to large IR drop on the main switch and synchronous rectifier. The slope compensation signal reduces the peak inductor current as a function of the duty cycle to prevent sub-harmonic oscillations at duty cycles greater than 50%. Conversely the current limit increases as the duty cycle decreases.APPLICATION INFORMATIONOutput Voltage SettingThe external resistor divider sets the output voltage (see Figure 3). The feedback resistor R1 also sets the feedback loop bandwidth with the internal compensation capacitor (see Figure 1). Choose R1 around 500k Ω for optimal transient response. R2 is then given by:1V6.0V 1R 2R OUT−=Table 1—Resistor Selection vs. OutputVoltage SettingV OUT R1 R2 1.2V 499k Ω (1%) 499k Ω (1%) 1.5V 499k Ω (1%) 332k Ω (1%) 1.8V 499k Ω (1%) 249k Ω (1%) 2.5V499k Ω (1%)158k Ω (1%)Inductor SelectionA 1µH to 10µH inductor with DC current rating at least 25% higher than the maximum load current is recommended for most applications. For best efficiency, the inductor DC resistance shall be <200m Ω. See Table 2 for recommended inductors and manufacturers. For most designs, the inductance value can be derived from the following equation:()OSCL IN OUT IN OUT f I V V V V L ×∆×−×=where ∆I L is Inductor Ripple Current. Choose inductor ripple current approximately 30% of the maximum load current, 800mA.The maximum inductor peak current is:2I I I LLOAD )MAX (L ∆+= Under light load conditions below 100mA, larger inductance is recommended for improved efficiency.

The input capacitor impedance at the switching frequency shall be less than input source impedance to prevent high frequency switching current passing to the input. Ceramic capacitors with X5R or X7R dielectrics are highly recommended because of their low ESR and small temperature coefficients. For most applications, a 4.7µF capacitor is sufficient. Output Capacitor SelectionThe output capacitor keeps output voltage ripple small and ensures regulation loop stable. The output capacitor impedance shall be low at the switching frequency. Ceramic capacitors with X5R or X7R dielectrics are recommended.
