General Description

BD9B333GWZ is a synchronous buck DC/DC converter

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.

BD9B333GWZ achieves the high power density and offer

a small footprint on the PCB by employing small CSP

package.
