DC2535A 应用手册
1Rev. 0DESCRIPTIONLT8653SDual Channel 2A, 42V, Synchronous Step-DownSilent Switcher with 6.2μA Quiescent CurrentDemonstration circuit 2535A is a 42V, dual channel, 2A synchronous step-down regulator featuring the L T ®8653S . The LT8653S is a compact, high efficiency, high speed syn-chronous monolithic step-down switching regulator which features the second generation Silent Switcher ® technology that minimizes EMI and reduces PCB layout sensitivity. The demo board is designed for two outputs: 5V and 3.3V from a 5.5V to 42V input. Each output can source up to 2A continuous current at the same time. The wide input range allows a variety of input sources, such as automo-tive batteries and industrial supplies. The integrated power switches and other necessary circuitry reduce the external component count and simplify design. Selectable spread spectrum mode of operation can further improve EMI/EMC performance. Ultralow quiescent current in Burst Mode ® operation achieves high efficiency at very light loads.The DC2535A demo board is 3" by 3" in size and has four layers with 2oz copper on the outer layers and 1oz cop-per on the inner layers. The DC2535A operates at 2MHz switching frequency by default to minimize solution size. The LT8653S is assembled in a small thermally enhanced 4mm × 3mm LQFN package. The IC temperature rises about 50°C when both channels operate at full load, 2A each, with the default switching frequency of 2MHz.The jumper JP2 on the demo board determines the con-figuration of the SYNC pin of the LT8653S. By default, the SYNC pin on the demo board is grounded for lowAll registered trademarks and trademarks are the property of their respective owners.PERFORMANCE SUMMARYripple Burst Mode operation. Moving JP2 to FCM W/SSM enables the spread spectrum mode of operation by tying the SYNC pin to VCC pin. To synchronize to an external clock, move JP2 to FCM W/O SSM OR SYNC position and apply the external clock on the SYNC turret.The jumpers JP3 and JP4 on the demo board determine the configuration of the output voltage select bit pins D0 and D1. On the DC2535A, the D0 and D1 pins are by default floating. This combination connects internal feed-back resistor divider between the FB1/FB2 pins and the error amplifier which means that FB1 and FB2 pins are regulated to 5V and 3.3V respectively. On the DC2535A, FB1/FB2 pins are by default connected through 0Ω resis-tors to the output nodes. Refer to the LT8653S data sheet for more information on the D0 and D1 pin settings.The demo board has an EMI filter installed. The EMI per-formance of the demo board (with EMI filter) is shown in Figure 1 and Figure 2. The black lines in Figure 2 are CISPR 25 class 5 limits. To achieve EMI/EMC performance as shown in Figure 2, the input EMI filter is required and the input voltage should be applied at VEMI terminal.The LT8653S data sheet gives a complete description of the part, operation and application information. The data sheet must be read in conjunction with this manual for demo circuit 2535A.Design files for this circuit board are available .Specifications are at T A = 25°CSYMBOL PARAMETER CONDITIONSMIN TYPMAX UNITSV IN Input Supply Range 5.542V V OUT1Output1 Voltage4.855.2V I OUT1Maximum Output1 Current 2A V OUT2Output2 Voltage3.168 3.33.432V I OUT2Maximum Output2 Current 2A f SW Switching Frequency 1.852 2.15MHz EFEEfficiency at DCV IN = 12V, I OUT1 = 1A, I OUT2 = 1A93.1%Figure 2. Radiated EMI Performance (CISPR 25 Radiated Emission Test with Class 5 Peak Limits)2Rev. 03Rev. 0QUICK START PROCEDUREFigure 3. Proper Measurement Equipment SetupFigure 4. Measure Output RippleDemonstration circuit 2535A is easy to set up to evalu-ate the performance of the LT8653S. Refer to Figure 3 for proper measurement equipment setup and follow the procedure below:NOTE: When measuring the input or output voltage rip-ple, care must be taken to avoid long ground lead on the oscilloscope probe. Measure the output voltage ripple by touching the probe tip directly across the VOUT and GND terminals. See Figure 4 for the proper measurement technique.1. Check that JP3 and JP4 are placed on the FLOAT position.2. Check that JP2 are placed on BURST position.3. With power off, connect the input power supply to VEMI and GND. If the EMI/EMC performance is not important, connect the input power supply to VIN and GND.4. With power off, connect the loads from VOUT1 to GND, and VOUT2 to GND.5. Turn on the power at the input.NOTE: make sure that the input voltage never exceeds 42V.6. Check for proper output voltages: V OUT1 = 5V, V OUT2 = 3.3V. NOTE: If there is no output, temporarily disconnect the load to make sure that the load is not set too high.7. Once the proper output voltages are established, adjust the load within the operating ranges and observe the output voltage regulation, ripple voltage, efficiency and other parameters.8. An external clock can be added to the SYNC terminal when SYNC function is used (JP2 on the FCM W/O SSM OR SYNC position). Please make sure that R12 resistor should be chosen to set the LT8653S switching frequency equal to or below the lowest synchronization frequency. JP2 can also set the LT8653S in spread spectrum mode (JP2 on the FCM W/SSM position).OUTPARTS LISTITEM QTY REFERENCE PART DESCRIPTION MANUFACTURER/PART NUMBERRequired Circuit Components11C2CAP., 4.7µF, X7R, 50V, 10%, 1206MURATA, GRM31CR71H475KA12L24C5, C9, C17, C23CAP., 1µF, X7R, 10V, 10%, 0603MURATA, GRM188R71A105KA61D32C6, C12CAP., 10µF, X5R, 10V, 10%, 0603TDK, C1608X5R1A106K080AC41C10CAP., 47µF, X5R, 10V, 10%, 1210MURATA, GRM32ER61A476KE20K51C11CAP., 100µF, X5R, 10V, 20%, 1210MURATA, GRM32ER61A107ME20L62C15, C16CAP., 10nF, X7R, 25V, 10%, 0603MURATA, GRM188R71E103KA01D72L1, L2INDUCTOR, 2.2µH, XFL4020COILCRAFT, XFL4020-222ME81R1RES., 1M, 1/10W, 1%, 0603VISHAY, CRCW06031M00FKEA94R4, R5, R13, R14RES., 0Ω, 1/10W, 0603VISHAY, CRCW06030000Z0EA102R10, R11RES., 100k, 1/10W, 1%, 0603VISHAY, CRCW0603100KFKEA111R12RES., 15k, 1/10W, 1%, 0603VISHAY, CRCW060315K0FKEA121U1I.C., STEP-DOWN SWITCHER, LQFN ANALOG DEVICES, LT8653SEV#PBF Additional Demo Board Circuit Components11C1CAP., ALUM, 22µF, 63V, 20%SUN ELECT., 63CE22BS20C7, C8CAP., OPTION, 060332C3, C4 (OPT)CAP., 0.1µF, X7R, 50V, 10%, 0402MURATA, GRM155R71H104KE14J40C13, C14, C21, C22 (OPT)CAP., OPTION, 060353C18, C25, C26CAP., 1µF, X5R, 50V, 10% 0603MURATA, GRM188R61H105KAALD62C19, C20CAP., 10µF, X7R, 50V, 10% 1210MURATA, GRM32ER71H106KA12L71FB1CHIP BEAD, 0805TDK, MPZ2012S101A81L3INDUCTOR, 220nH VISHAY, IHLP1616ABERR22M0191R2RES., 0Ω, 1/10W, 0603VISHAY, CRCW06030000Z0EA100R3, R6, R7, R8, R9 (OPT)RES, OPTION, 0603Hardware: For Demo Board Only116E1-E16TESTPOINT, TURRET, 0.094"MILL-MAX, 2501-2-00-80-00-00-07-0 21JP1HEADER 3 PIN 0.079 SINGLE ROW WURTH ELEKTRONIK, 6200031112133JP2, JP3, JP4HEADER 3 PIN 0.079 DOUBLE ROW WURTH ELEKTRONIK, 6200062112144xJP1, xJP2, xJP3, xJP4SHUNT, 0.079" CENTER WURTH ELEKTRONIK, 6080021342154MH1-MH4STAND-OFF, NYLON, 9.5mm WURTH ELEKTRONIK, 7029330004Rev. 05Rev. 0Information furnished by Analog Devices is believed to be accurate and reliable.

村田低ESR电容器：ESR是Equivalent Series Resistance的缩写，即“等效串联电阻”。理想的电容自身不会有任何能量损失，但实际上，因为制造电容的材料有电阻，电容的绝缘介质有损耗。这个损耗在外部，表现为就像一个电阻跟电容串联在一起，所以就称为“等效串联电阻”。有的电容还会标出ESR值（等效串联电阻），ESR越低，损耗越小，输出电流就越大，电容器的品质越高
