ISL99140IRZ-T 40A DrMOS Power Module with Integrated Diode Emulation and Thermal Warning Output QFN40 spot stock

Product Descriptions

The ISL99140 is a high performance DrMOS power module  designed for high frequency power conversion. By combining a  high performance FET driver and MOSFETs in an advanced  package, high density DC/DC converters can 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 ISL99140 features a three-state PWM input that, working  together with Intersil’s multiphase PWM controllers, will  provide a robust solution in the event of abnormal operating  conditions. To further support robust applications, the  ISL99140 features a thermal warning output that can be used  to notify the power system of an impending thermal fail event.

The ISL99140 supports high efficiency operation not only at  heavy loads, but also at light loads through its diode emulation  capability. Diode emulation can be disabled for those  applications in which variable frequency operation is not  desired at light loads.
