MAXM17761EVKIT#: 5V @ 1A, 10 ~ 76V in

The MAXM17761 5V-output evaluation kit (EV kit) provides a proven design to evaluate the MAXM17761 high voltage, high-efficiency, synchronous step-down DC-DC converter. The EV kit is preset for 5V output at load currents up to 1A and features a 537kHz switching frequency for optimum efficiency and component size. The EV kit features an adjustable input undervoltage lockout, adjustable soft-start, open-drain RESET signal, and external frequency synchronization.

The MAXM17761 is a high-efficiency, high voltage step down power module with dual integrated MOSFETs that operate over a 4.5V to 76V input supports a programmable output voltage from 0.8V to 5V, delivering up to 1A current. The module integrates all the necessary components required for switching converter. The feedback voltage regulation accuracy meets ±1.5% over load, line, and temperature. The device uses a peak-current-mode control scheme. An internal transconductance error amplifier generates an error voltage. The error voltage sets the duty cycle using a PWM comparator, a high-side current-sense amplifier, and a slope compensation generator.
