Overview
Description
The ISL8502AEVAL1Z evaluation board is used to evaluate the ISL8502A synchronous buck controller with internal MOSFETs.
The ISL8502A is a synchronous buck controller with internal MOSFETs packaged in a small 4mm x 4mm QFN package. The device 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 provides a much more efficient solution than a linear regulator. Power-good (PGOOD) delay for the ISL8502A has been decreased to 1ms typical (at 500kHz switching frequency) compared to 250ms (at 500kHz) for the ISL8502.
