DESCRIPTION
The IR3537/CHL8510 is a high efficiency gate driver which can switch both high‐side and low‐side N‐channel external MOSFETs in a synchronous buck converter. It is intended for use with International Rectifier’s Digital PWM controllers to provide a total voltage regulator (VR) solution for today’s advanced puting applications.
The IR3537/CHL8510 low‐side driver is capable of rapidly switching large MOSFETs with low RDS(on) and large input capacitance used in high efficiency designs.
The IR3537/CHL8510 Features
individual control of both the high‐and low‐side gate drive voltages from 4.5V to 13.2V. This enables the optimization of switching and conduction losses in the external MOSFETs. When used with IR’s proprietary Variable Gate Drive (VGD) technology, a significa...
