1.5A 1.6MHz Low Quiescent Current High
Efficiency Synchronous Buck Regulator
ISL9107 and ISL9108 are 1.6MHz synchronous step-down
regulators with integrated power switches capable of
delivering 1.5A output current, which is ideal for powering
low-voltage microprocessors in compact devices such as
PDAs and cellular phones. These devices are 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.
1.6MHz pulse-width modulation (PWM) switching frequency
allows using small external components. They have flexible
operation mode selection of forced PWM mode and Skip
(Low I Q ) mode with typical 17 μ A quiescent current for
highest light load efficiency to maximize battery life.
The ISL9107 and ISL9108 integrate a pair of low
ON-resistance P-Channel and N-Channel MOSFETs to
maximize efficiency and minimize external component
count.
The ISL9107 offers a typical 215ms Power-Good (PG) timer
when powered up. The timer output can be reset by RSI.
When shutdown, ISL9107 and ISL9108 discharge the output
capacitor. Other features include internal digital soft-start,
enable for power sequence, overcurrent protection, and
thermal shutdown.
The ISL9107 and ISL9108 are offered in 8 Ld 2mmx3mm
DFN package with 0.9mm typical height. The complete
converter can occupy less than 1cm 2 area.
