The ISL8036CRSHEVAL1Z and ISL8036ACRSHEVAL1Z evaluation boards are intended for use by individuals with requirements for point-of-load (POL) applications sourcing from 2.85V to 6V. These boards are used to demonstrate the performance of the ISL8036/ISL8036A low quiescent current mode converter in a current sharing configuration.

The ISL8036 and ISL8036A are integrated power controllers rated for dual 3A output current or current sharing operation with a 1MHz (ISL8036)/2.5MHz (ISL8036A) step-down regulator, which is ideal for any low power low-voltage applications. The channels are 180° out-of-phase for input RMS current and EMI reduction. They are optimized for generating low output voltages down to 0.8V each.
