ISL8502AEVAL1Z, ISL8502EVAL1Z

2A Synchronous Buck Regulator with Integrated MOSFETs Evaluation Board

Description

The ISL8502AEVAL1Z, ISL8502EVAL1Z boards evaluate the ISL8502 is a synchronous buck controller with internal MOSFETs.

The ISL8502 and ISL8502A are synchronous buck controllers with internal MOSFETs packaged in a small 4mmx4mm QFN package. They 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. PGOOD delay for ISL8502A has been decreased to 1ms typical (at 500kHz switching frequency) compared to 250ms (at 500kHz) for ISL8502.
