BD9B500MUV-E2 by Rohm

2.7V to 5.5V Input, 5.0A Integrated MOSFET Single Synchronous Buck DC/DC Converter


BD9B500MUV is a synchronous buck switching regulator with built-in low on-resistance power MOSFETs. This IC, which is capable of providing current up to 5A, 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.
