General Description

BD9E200FP4-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. BD9E200FP4-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.
