Overview
DATASHEET ISL9105 600mA Low Quiescent Current 1.
6MHz High Efficiency Synchronous Buck Regulator FN6415 Rev 2.
00 March 28, 2008 ISL9105 is a 600mA, 1.
6MHz step-down regulator that is ideal for powering low-voltage microprocessors in handheld 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 for the use of a single Li+ cell, three NiMH cells or a regulated 5V input.
It has a guaranteed minimum output current of 600mA.
1.
6MHz pulse-width modulation (PWM) switching frequency allows for use of small external components.
It has flexible operation mode selection of forced PWM mode and low IQ mode with typical 25µA quiescent current for highest light load efficiency to maximize battery life.
The ISL9105 includes a pair of low ON-resistance P-Channel and N-Channel internal MOSFETs to maximize efficiency and minimize external component count.
100% duty-cycle operation allows less ...
