General Description

BD9D300MUV is a synchronous buck switching regulator

with built-in low on-resistance power MOSFETs. This

integrated circuit (IC) is capable of providing current up to

3 A. It operates high oscillating frequency with low

inductance. It has original on-time control system which

can operate low power consumption in light load condition.

This IC is ideal for reducing standby power consumption

of equipment.
