ISL9106
1.2A 1.6MHz Low Quiescent Current High Efficiency Synchronous Buck Regulator
FN6509 Rev 0.00 June 29, 2007
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 (PWM) switching frequency allows using small external components. It has flexible operation mode selection of forced PWM mode and Skip (Low IQ) mode with typical 17A quiescent current for highest light load efficiency to maximize battery life.
