`MAX5035
`1A, 76V, High-Efficiency MAXPower Step-Down DC-DC Converter
`
`DESCRIPTION
`
`The MAX5035 easy-to-use, high-efficiency, high-voltage, step-down DC-DC converter operates from an input
`voltage up to 76V and consumesonly 350uA quiescentcurrent at no load. This pulse-width modulated (PWM)
`converter operatesat a fixed 125kHz switching frequency at heavy loads, and automatically switches to pulse-
`skipping mode to provide low quiescent current and highefficiency at light loads. The MAX5035 includes
`internal frequency compensation simplifying circuit implementation. The device uses aninternal low-on-
`resistance, high-voltage, DMOStransistor to obtain high efficiency and reduce overall system cost. This device
`includes undervoltage lockout, cycle-by-cycle currentlimit, hiccup mode output short-circuit protection, and
`thermal shutdown.
`
`The MAX5035delivers up to 1A output current. External shutdownis included, featuring 10uA (typ) shutdown
`current. The MAX5035A/B/C versions have fixed output voltages of 3.3V, 5V, and 12V, respectively, while the
`MAX5035Dfeatures an adjustable output voltage from 1.25V to 13.2V.
`
`The MAX5035is available in space-saving 8-pin SO and 8-pin plastic DIP packages and operates over the
`industrial (0°C to +85°C) temperature range.
