SI4728CY Datasheet N-channel MOSFET

Manufacturer: Vishay

Overview: .. Si4728CY Vishay Siliconix N-Channel Synchronous MOSFETs with.

General Description

The Si4728CY 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 design to be used with any single output PWM IC or ASIC to produce a highly efficient low cost synchronous rectifier converter.
