Product Details

The MAX17570A/MAX17570D evaluation kits (EV kits) pr-ovide proven designs to evaluate the performance of the MAX17570A/MAX17570D high-voltage, high-efficiency, synchronous step-down DC-DC converters. The MAX175-70A/MAX17570D EV kits operate over a 4.5V to 60V input range and can deliver up to 300mA at a fixed 3.3V output. The MAX17570A operates in PWM mode at all loads and the MAX17570D operates in PFM mode at light loads.

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