General Description

BD9S209NUX-C is a synchronous buck DC/DC

Converter with built-in low On Resistance power

MOSFETs. It is capable of providing current up to 2 A.

Small inductor is applicable due to high switching

frequency of 2.2 MHz. It is a current mode control

DC/DC Converter and features high-speed transient

response. It has a built-in phase compensation circuit.

Applications can be created with a few external

components.
