ISL8560MR

DC/DC Power Switching Regulator

Device is no longer available or supported, and production has been discontinued.

Product Status: EOL

OVERVIEW

The ISL8560MREP is a step down DC/DC power switching regulator which accepts 9.0V to 60V input and provides a 2A output current. The output voltage can be set in the range between 1.21V and 55V by means of an external divider. The device uses an internal power DMOS transistor with a typical rDS(ON) of 0.19Ω to obtain very high efficiency and high switching speed. A switching frequency in the range of 100kHz to 600kHz can be realized (the maximum power dissipation of the various packages must be observed). Notable features of this next generation of DC/DC converter includes pulse-by-pulse current limit for FET protection, hiccup mode for short circuit protection, voltage feedforward regulation, Frequency SYNC, soft-start, low standby current of 60µA typical in the disabled state, and thermal shut-down. The device is available in a 20 Ld QFN package.

Device Information
