2.7V to 5.5V Input, 3A Integrated MOSFET

Single Synchronous Buck DC/DC Converter

BD9A301MUV-LB

General Description

Key Specifications

This is the product guarantees long time support in

Industrial market. BD9A301MUV-LB is a synchronous

buck switching regulator with built-in low on-resistance

power MOSFETs. It is capable of providing current up to

3A.The SLLM^TMcontrol provides excellent efficiency

characteristics in light-load conditions which make the

product ideal for equipment and devices that demand

minimal standby power consumption. The oscillating

frequency is high at 1MHz using a small value of

inductance. It is a current mode control DC/DC converter

and features high-speed transient response. Phase

compensation can also be set easily.
