ISL8560 FN9244
Rev 7.00
September 19, 2008 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 0.19пЃ— 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 60ВµA typical in the disabled state, and thermal shut-down.
The device is available in a 20 Ld QFN package. Features Voltage feedforward mode Step down DC/DC supporting up to 2A Input voltage range of 9.0V to 60V Internal reference of 1.21V В±1% Adjustable output voltage range of 1.21V to 55V Adjustable switching frequency 100kHz to 600kHz Frequency SYNC pin Zero load current operation Pulse-by-pulse mode current limit and Hiccup mode Low standby current of 60ВµA typical Thermal shut-down Ordering Information
