1.2A 1.6MHz Low Quiescent Current High
Efficiency Synchronous Buck Regulator
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 I
highest light load efficiency to maximize battery life.
The ISL9106 integrates a pair of low ON-resistance
P-Channel and N-Channel MOSFETs to maximize efficiency
and minimize external component count.
The ISL9106 offers a typical 215ms Power-Good (PG) timer
when powered up. The timer output can be reset by RSI.
When shutdown, ISL9106 discharges the output capacitor.
Other features include internal digital soft-start, enable for
power sequence, overcurrent protection, and thermal
shutdown.
The ISL9106 is offered in 10 Ld 3mmx3mm DFN package
with 0.9mm typical height. The complete converter can
occupy less than 1cm
Ordering Information
NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
