I. Device Description

A. General

The MAX1951 high-efficiency, DC-to-DC step-down switching regulator delivers up to 1.5A of output current. The

the MAX1951 ideal for on-board postregulation applications. The MAX1951 total output error is less than 1% over

load, line, and temperature.

The MAX1951 operates at a fixed frequency of 1MHz with an efficiency of up to 94%. The high operating frequency

minimizes the size of external components. Internal soft-start control circuitry reduces inrush current. Short-circuit

and thermal-overload protection improve design reliability.
