Overview
DATASHEET ISL9104, ISL9104A 500mA 4.
3MHz Low IQ High Efficiency Synchronous Buck Converter FN6829 Rev 5.
00 The ISL9104, ISL9104A is a 500mA, 4.
3MHz 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 4.
3MHz 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 ISL9104, ISL9104A includes a pair of low ON-resistance P-Channel and N-Channel internal MOSFETs to maximize system ef...
