产品详情

The MAX17570C/MAX17570F evaluation kits (EV kits) provide proven designs to evaluate the performance of the MAX17570C/MAX17570F high-voltage, high-efficiency, synchronous step-down DC-DC converters. The MAX175-70C/MAX17570F EV kits operate over a 15V to 60V input range and can deliver up to 300mA at an adjustable 12V output. The MAX17570C operates in PWM mode at all loads and the MAX17570F operates in PFM mode at light loads.

The EV kits feature an adjustable input undervoltage lock-out, open-drain RESET, overcurrent protection, external frequency synchronization, and thermal shutdown. The MAX17570 IC data sheet provides a complete description of the part and should be read in conjunction with this EV kit data sheet before operating these EV kits.
