Synchronous Step-Down Converter

BD9052xEFJ-C Series

●General Description

●Key Specifications

■ Input voltage range

■ Output voltage

The BD9052xEFJ-C series is

synchronous

2.69V～5.5[V]

rectification type step-down DC/DC converter with a

2.25MHz fixed frequency that operates in with an input

voltage range of 2.69V-5.5V. It has an integrated

feedback resistor that

of 1.2V/1.5V/1.8V and a phase compensation constant.

Applications can be created with a minimum of three

external components.

and Nch output MOSFET can supply a maximum output

current of 2A.
