DC1286A-B - LTC3862EGN-1 Demo Board | 8V to 36VIN, 48VOUT @ 5A, Multiphase Boost Controller

Demonstration circuit 1286A is DC/DC boost converter featuring the LTC®3862EGN/-1 constant frequency current mode boost controllers. The DC1286A-A (LTC3862) operates over 5V to 36V input and provides 2A-5A of output current at 48V output. The DC1286A-B (LTC3862-1, higher VIN min and higher gate drive) operates over 8V to 36V input and provides 3A-5A of output current at 48V output. The 200kHz constant frequency operation results in small and efficient circuit. The converter provides high output voltage accuracy (typically ±3%) over wide load range with no minimum load requirement. The demonstration circuit can be easily modified to generate different output voltages.
