ISL9105
600mA Low Quiescent Current 1.6MHz
High Efficiency Synchronous Buck
Regulator
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 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 using small external components. It has flexible
operation mode selection of forced PWM mode and low IQ
mode with typical 25
μ
A 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 than 200mV dropout voltage at 600mA
output current.
The ISL9105 offers a typical 216ms Power-On-Reset (POR)
timer at power-up. The timer output can be reset by RSI.
When shutdown, ISL9105 discharges the output capacitor.
Other features include internal digital soft-start, enable for
power sequence, overcurrent protection, and thermal
shutdown.
The ISL9105 is offered in a 2mmx3mm 8 Ld DFN package
with 1mm maximum height. The complete converter
occupies less than 1cm
2
area.

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.
