500mA, 76V, High-Efficiency, MAXPower Step-Down DC-DC Converter
General Description
The MAX5033 easy-to-use, high-efficiency, high-voltage, step-down DC-DC converter operates from an input voltage up to 76V and consumes only 270μA quiescent current at no load. This pulse-width modulated (PWM) converter operates at a fixed 125kHz switching frequency at heavy loads, and automatically switches to pulseskipping mode to provide low quiescent current and high efficiency at light loads. The MAX5033 includes internal frequency pensation simplifying circuit implementation. The device uses an internal low-onresistance, high-voltage, DMOS transistor to obtain...
