DESCRIPTION

The Si4724CY N-Channel synchronous MOSFET with

break-before-make (BBM) is a high speed driver designed to

operate in high frequency DC/DC switchmode power

supplies. It’s purpose is to simplify the use of N-Channel

MOSFETs in high frequency buck regulators. This device is

designed to be used with any single output PWM IC or ASIC

to produce a highly efficient low cost synchronous rectifier

converter. A synchronous enable pin (disable = low,

enable = high) controls the synchronous function for light

load conditions.

The Si4724CY is packaged in Vishay Siliconix’s high

performance LITTLE FOOT? SO-16 package.
