40A DrMOS Power Module with Integrated Diode
Emulation and Thermal Warning Output
ISL99140
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 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 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 may 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 via its diode emulation
capability. Diode emulation can be disabled for those
applications where variable frequency operation is not desired
at light loads.
