概要
説明
The ISL8036ADUALEVAL1Z evaluation board is intended for use by individuals with requirements for point-of-load (POL) applications sourcing from 2.85V to 6V. This evaluation board is used to demonstrate the performance of the ISL8036A low quiescent current mode converters.
The ISL8036A is an integrated power controller rated for dual 3A output current or current sharing operation with a 2.5MHz 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. This device is optimized for generating low output voltages down to 0.8V each.
