1A Synchronous Buck Regulator

With Integrated Inductor

RoHS Compliant

Halogen Free

Product Overview

Featuring Integrated Inductor Technology

The Ultra-Low-Profile EN5311QI is targeted to

applications where board area and profile are

critical. EN5311QI is a complete power

conversion solution requiring only two low cost

ceramic MLCC caps. Inductor, MOSFETS,

PWM, and compensation are integrated into a

tiny 5mm x 4mm x 1.1mm QFN package. The

EN5311QI is engineered to simplify design and

A 3-pin VID output voltage selector provides

seven pre-programmed output voltages along

with an option for external resistor divider.

Output voltage can be programmed on-the-fly

to provide fast, dynamic voltage scaling.
