4.5 V to 28 V Input, 2.0 A Integrated MOSFET

Single Synchronous Buck DC/DC Converter

BD9E202FP4-Z

General Description

Key Specifications

◼ Input Voltage Range:

◼ Output Voltage Range:

◼ Output Current:

BD9E202FP4-Z is a single synchronous buck DC/DC

converter with built-in low on-resistance power MOSFETs.

The Light Load Mode control provides excellent efficiency

characteristics in light-load conditions, which make the

product ideal for equipment, and devices that demand

minimal standby power consumption. BD9E202FP4-Z is a

current mode control DC/DC converter and features good

transient response. It includes internal phase compensation.

It achieves the high power density and offers a small

footprint on the PCB by employing small package.
