Maxim Integrated MAX5033
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 compensation simplifying circuit implementation.| Part No. | MAX5033 |

GENERAL DESCRIPTION
The device uses an internal low-onresistance, 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. The MAX5033 delivers up to 500mA output current. The output current may be limited by the maximum power dissipation capability of the package. External shutdown is included, featuring 10μA (typ) shutdown current. The MAX5033A/B/C versions have fixed output voltages of 3.3V, 5V, and 12V, respectively, while the MAX5033D features an adjustable output voltage, from 1.25V to 13.2V. The MAX5033 is available in space-saving 8-pin SO and 8-pin plastic DIP packages and operates over the automotive (-40°C to +125°C) temperature range.APPLICATIONS
