Overview
DATASHEET ISL9103, ISL9103A 500mA 2.
4MHz Low IQ High Efficiency Synchronous Buck Converter FN6828 Rev 3.
00 December 9, 2015 The ISL9103, ISL9103A is a 500mA, 2.
4MHz 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 6V allowing the use of a single Li+ cell, three NiMH cells or a regulated 5V input.
It has guaranteed minimum output current of 500mA.
A high switching frequency of 2.
4MHz pulse-width modulation (PWM) allows using small external components.
Under light load condition, the device operates at low IQ skip mode with typical 20µA quiescent current for highest light load efficiency to maximize battery life, and it automatically switches to fixed frequency PWM mode under heavy load condition.
The ISL9103, ISL9103A includes a pair of low ON-resistance P-Channel and N-Channel internal MOSFETs to m...
