ISL8560MREP is Intersil's step down DC/DC power switching regulator, which accepts input voltage from 9.0V to 60V and provides 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.
The ISL8560MREP is a DC/DC step‑down regulator that accepts 9.0 V to 60 V input and provides up to 2 A output current. The output voltage is adjustable from 1.21 V to 55 V using an external divider, and the device features pulse‑by‑pulse current limit, hiccup mode, voltage feed‑forward regulation, frequency sync, soft‑start, low standby current, and thermal shutdown.
The regulator is offered in a 20‑lead QFN package (6 × 6 mm) and is qualified for military‑temperature operation from –55 °C to +125 °C. Ordering information, mechanical drawings, and detailed dimensions are provided in the datasheet.
