DC/DC Power Switching Regulator
The ISL8560 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.
