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.
