DATASHEET ISL8502A 2A Synchronous Buck Regulator with Integrated MOSFETs FN7940 Rev 0.00 October 21, 2011 The ISL8502A is a synchronous buck controller with internal MOSFETs packaged in a small 4mmx4mm QFN package.

The ISL8502A can support a continuous load of 2A and has a very wide input voltage range.

With the switching MOSFETs integrated into the IC, the complete regulator footprint can be very small and provide a much more efficient solution than a linear regulator.

The ISL8502A is capabl

ISL8502A Features

* a bi-directional Enable pin that allows the part to pull the enable pin low during fault detection. PGOOD delay for ISL8502A has been decreased to 1ms typical (at 500kHz switching frequency) compared to 250ms (at 500kHz) for ISL8502. Features

* Up to 2A Continuous Output Current

* I
