Description

The Enpirion EN5311QI represents a revolution in low-power switching converters. The total solution footprint is 38mm2, without compromising efficiency. Requiring two external components, the EN5311QI makes regulator design a breeze.

A complete power system-on-a-chip (PowerSoC), the EN5311QI integrates power switches, Inductor, gate drive, controller, and loop compensation in a tiny 5 mm x 4 mm package. The 1.1mm profile and small footprint enables the use of this part where space is at a premium.

The EN5311QI utilizes a 3-pin VID output voltage selector that allows the designer to choose one of seven pre-defined output voltage levels; or an external voltage divider can be employed to set the output voltage.
