RP510L Series

4 A Forced PWM Step-down DC/DC Converter with Synchronous Rectifier

No. EA-366-180125

OVERVIEW

The RP510L is a low input voltage step-down DC/DC converter that operates from 2.5 V to 5.5 V and provides up to 4

A of output current

(1)

. It is suitable for power supply of SoC (System-on-a-chip). It is also available in a foldback type

overcurrent protection which automatically recovers to the normal state after the cause of overcurrent is removed.

•

KEY BENEFITS

The realization of the high-density mounting by the adoption of a small package DFN3030-12.

A simplification of the power sequencing by power-good and adjustable soft-start functions.

Selectable overcurrent protection: Latch type or Foldback type.
