The MAX5035BUSA+T from Maxim Integrated Products is a 1A, 76V, high efficiency MAXPower step down DC to DC converter in 8 pin NSOIC package. The MAX5035 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 pulse skipping mode to provide low quiescent current and high efficiency at light loads. The MAX5035 includes internal frequency compensation simplifying circuit implementation. The device uses an internal low on-resistance, high-voltage, DMOS transistor to obtain high efficiency and reduce overall system cost. The output current may be limited by the maximum power dissipation capability of the package. Typical application includes automotive, consumer electronics, industrial and distributed power.
