Monolithic 1A Step-Down Regulator with
Low Quiescent Current
The ISL97536 is a synchronous, integrated FET 1A
step-down regulator with internal compensation. It operates
with an input voltage range from 2.5V to 6V, which
accommodates supplies of 3.3V, 5V, or a Li-Ion battery
source. The output can be externally set from 0.8V to V
IN
with a resistive divider.
The ISL97536 features PWM control with a 1.4MHz typical
switching frequency. The typical no load quiescent current is
only 500碌A(chǔ). Additional features include a 100ms Power-On-
Reset output, <1碌A(chǔ) shutdown current, short-circuit
protection, and over-temperature protection.
The ISL97536 is available in the 10 Ld MSOP package,
making the entire converter occupy less than 0.15in
2
of PCB
area with components on one side only. The 10 Ld MSOP
package is specified for operation over the full -40擄C to
+85擄C temperature range.

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.
