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.
