General Description

BD9S11xNUX-C series is a synchronous buck DC/DC

Converter with built-in low On Resistance power

MOSFETs. It is capable of providing current up to 1 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 an integrated feedback resistor that

sets the output voltage to 1.2 V/1.8 V and a built-in

phase compensation circuit. Applications can be

created with a few external components.
