25A/35A DrMOS Module with Diode Emulation and PS4

The ISL99125B and ISL99135B are high-performance DrMOS power modules designed for high-frequency power conversion. By combining a high-performance FET driver and MOSFETs in an advanced package, high-density DC/DC converters may be created. Combined with an Intersil PWM controller, a complete voltage regulator solution can be created with reduced external components and minimum overall PCB real estate.

The ISL99125B and ISL99135B feature a three-state PWM input that, working together with Intersil’s 5V PWM controllers (such as ISL6398, ISL9585x, ISL637x, ISL633x, ISL636x, and ISL68201), will provide a robust solution in the event of abnormal operating conditions.
