MAX17501HTEVKIT#: 2.5V @ 500mA, 4.5 ~ 60V in

The MAX17501H EV kit provides a proven design to evaluate the MAX17501H high-efficiency, high-voltage, synchronous step-down DC-DC converter in a TDFN package. The EV kit uses the MAX17501H device to generate 2.5V at load currents up to 500mA from a 4.5V to 60V input supply. The MAX17501H features a forced-PWM control scheme that provides constant switching frequency operation at all load and line conditions.

The low-resistance, on-chip MOSFETs ensure high efficiency at full load and simplify the layout. A programmable soft-start feature allows users to reduce input inrush current.

The device also incorporates an output enable/undervoltage lockout pin (EN/UVLO) that allows the user to turn on the part at the desired input voltage level. An open-drain RESET pin provides a delayed power-good signal to the system upon achieving
successful regulation of the output voltage.
