2.7V to 5.5V Input, 2.0A Integrated MOSFET Single Synchronous Buck DC/DC Converter - BD9B200MUV

BD9B200MUV is a synchronous buck switching regulator with built-in low on-resistance power MOSFETs. This IC, which is capable of providing current up to 2A, 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.
