The ISL8560EVAL2Z evaluation board is used to demonstrate the performance of the ISL8560 DC/DC power switching regulator.
The ISL8560 is a step-down DC/DC power switching regulator which accepts a 9V to 60V input, and provides up to 2A of output current. The output voltage can be set between 1.21V and 35V by means of an external resistor 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 DC/DC converter include pulse-by-pulse current limit for FET protection, hiccup-mode short circuit protection, voltage feed-forward, frequency SYNC, soft-start, a low standby current of 60μA typical in the disabled state, and thermal shut-down. The device is available in a 20 Ld QFN package.
