BD9E201FP4-ZTL

General Description

BD9E201FP4-Z is a single synchronous buck DC/DC 

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

BD9E201FP4-Z is a current mode control. It includes 

internal phase compensation. It achieves the high power 

density and offers a small footprint on the PCB by employing 

small package.
