Jul 20, 2017 40A DrMOS Power Module with Integrated Diode Emulation and Thermal
Warning Output
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. Features 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. Thermal warning output 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. Undervoltage lockout Related Literature Applications For a full list of related documents, visit our website
