Current Sharing 3A 2.5MHz High Efficiency Synchronous Buck Regulator Evaluation Boards


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

ISL8036, 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. It is optimized for generating low output voltages down to 0.8V each.
