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
device operates from an input voltage range of 2.6V to 5.5V and provides an output voltage from 0.8V to V
IN
, making
the MAX1951 ideal for on-board postregulation applications. The MAX1951 total output error is less than 1% over
load, line, and temperature.
The MAX1951 successfully meets the quality and reliability standards required of all Maxim products. In addition,
V. ........Quality Assurance Information
VI. .......Reliability Evaluation
IV. .......Die Information
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.
The MAX1951 provides an adjustable output from 0.8V to V
IN
. The device ia available in a space-saving 8-pin SO
package.
