ISL8009
1.5A Low Quiescent Current 1.6MHz High
Efficiency Synchronous Buck Regulator
ISL8009 is an integrated power controller rate for 1.5A,
1.6MHz step-down regulator that is ideal for any low power,
low-voltage applications. It is 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. It has a guaranteed
minimum output current of 1.5A. 1.6MHz pulse-width
modulation (PWM) switching frequency allows for using
small external components. It has flexible operation mode
selection of forced PWM mode and PFM mode with as low
as 17μA quiescent current for highest light load efficiency to
maximize battery life.
The ISL8009 includes a pair of low on-resistance P-Channel
and N-Channel internal MOSFETs to maximize efficiency
and minimize external component count. Duty-cycle
operation allows less than 400mV dropout voltage at 1.5A.
The ISL8009 offers a 200ms Power-On-Reset (POR) timer
at power-up. The timer output can be reset by RSI. When
shutdown, ISL8009 discharges the output capacitor through
a 100
Ω
resistor. Other features include internal digital soft-
start, enable for power sequence, overcurrent protection,
and thermal shutdown.
The ISL8009 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.
