Rohm : BD9B300: 3.0A Integrated MOSFET Buck DC/DC Converter

BD9B300MUV is a synchronous buck switching regulator with built-in low on-resistance power MOSFETs.

This IC, which is capable of providing current up to 3A, features fast transient response by employing constant on-time control system. It offers high oscillating frequency at low inductance. With its original constant on-time control method which operates low consumption at light-load, this product is ideal for equipment and devices that demand minimal stand-by power consumption.
