Infineon Technologies
12V High Performance Gate Driver
Package Type: 10‐pin DFN
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 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 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.
