BD9B301MUV-LB
BD9B301MUV-LB is Single Synchronous Buck DC/DC Converter manufactured by ROHM.
Description
This is the product guarantees long time support in Industrial market. BD9B301MUV-LB 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 standby power consumption.
