Maxim Integrated Products part MAX5035AASA-TG098
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 270ìA 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 lowon- resistance, high-voltage, DMOS transistor to obtain high efficiency and reduce overall system cost. This device includes undervoltage lockout, cycle-by-cycle current limit, hiccup mode output short-circuit protection, and thermal shutdown
