MAX17502FTEVKIT#: 5V @ 1A, 7 ~ 60 Vin, Buck

Summary

The MAX17502F evaluation kit (EV kit) provides a proven design to evaluate the MAX17502F high-efficiency, high voltage, synchronous step-down DC-DC converter. The EV kit uses the device to generate a fixed 5 V at load currents up to 1 A from a 7 V to 60 V input supply. The device features a forced-PWM control scheme that provides constant switching-frequency operation at all load and line conditions.

The MAX17502 high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs operates over a 4.5 V to 60 V input voltage range. It delivers output currents up to 1A at output voltages of 0.9 V to 92% VIN. The output voltage is accurate to within ±1.7% over -40°C to +125°C. The MAX17502 is available in compact TDFN and TSSOP packages. Simulation models are available.
