DC/DC Power Switching RegulatorThe ISL8560MREP is a step down DC/DC power switchingregulator which accepts 9.0V to 60V input and provides a 2Aoutput current. The output voltage can be set in the rangebetween 1.21V and 55V by means of an external divider.The device uses an internal power DMOS transistor with atypical rDS(ON) of 0.19Ω to obtain very high efficiency andhigh switching speed. A switching frequency in the range of100kHz to 600kHz can be realized (the maximum powerdissipaTIon of the various packages must be observed).Notable features of this next generaTIon of DC/DC converterincludes pulse-by-pulse current limit for FET protecTIon,hiccup mode for short circuit protecTIon, voltage feedforwardregulation, Frequency SYNC, soft-start, low standby currentof 60μA typical in the disabled state, and thermal shut-down.The device is available in a 20 Ld QFN package.Device InformationThe specifications for an Enhanced Product (EP) device aredefined in a Vendor Item Drawing (VID), which is controlledby the Defense Supply Center in Columbus (DSCC).“Hot-links” to the applicable VID and other supportingapplication information are provided on our website.
