ISL8033, Dual 3A Low Quiescent Current High Efficiency Synchronous Buck Regulator

DATASHEET ISL8033, ISL8033A Dual 3A Low Quiescent Current High Efficiency Synchronous Buck Regulator FN6854 Rev 2.00 March 24, 2011 ISL8033 is a dual integrated power controller rated for 3A per channel with a 1MHz step-down regulator that is ideal for any low power low-voltage applications.

The ISL8033A offers 2.5MHz operation for smaller more compacted design.

The channels are 180° out-of-phase for input RMS current and EMI reduction.

It is optimized for generating low output voltages down
