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 computing applications.

The IR3537/CHL8510 low-side driver is capable of rapidly

switching large MOSFETs with low R

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 significant improvement in efficiency is

observed across the entire load range.

The IR3537/CHL8510 can be configured to drive both the

high- and low-side switches from the unique IR fast Active

Tri-Level (ATL) PWM signal or a generic tri-state PWM

mode. The IR ATL mode allows the controller to disable

the high- and low-side FETs in less than 30ns without the

need for a dedicated disable pin. This improves VR

transient performance, especially during load release.

The integrated bootstrap diode reduces external

component count. The IR3537/CHL8510 also features

an adaptive non-overlap control for shoot-through

protection. This prevents cross conduction of both high-

side and low-side MOSFETs and minimizes body diode

conduction time to provide the best in class efficiency.
