® ISL9106 Data Sheet June 29, 2007 FN6509.0 1.2A 1.6MHz Low Quiescent Current High Efficiency Synchronous Buck Regulator ISL9106 is a 1.2A, 1.6MHz step-down regulator, which is ideal for powering low-voltage microprocessors in compact devices such as PDAs and cellular phones.

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

The supply voltage range is from 2.7V to 5.5V allowing the use of a single Li+ cell, three NiMH cells or a regulated 5V input.

1.6MHz pulse-width modulation
