FN6191.0
Monolithic 600mA Step-Down Regulator
with Low Quiescent Current
Features
2
• Less than 0.18in footprint for the complete 600mA
converter
The ISL8010 is a synchronous, integrated FET 600mA step-
down regulator with internal compensation. It operates with
an input voltage range from 2.5V to 5.5V, which
• Components on one side of PCB
• Max height 1.1mm MSOP10
accommodates supplies of 3.3V, 5V, or a Li-Ion battery
source. The output can be externally set from 0.8V to V
with a resistive divider.
• Power-Good (PG) output
IN
• Internally-compensated voltage mode controller
• Up to 95% efficiency
The ISL8010 features automatic PFM/PWM mode control, or
PWM mode only. The PWM frequency is typically 1.4MHz
and can be synchronized up to 12MHz. The typical no load
quiescent current is only 120µA. Additional features include
a Power-Good output, <1µA shutdown current, short-circuit
protection, and over-temperature protection.
• <1µA shutdown current
• 120µA quiescent current
• Hiccup mode overcurrent and over-temperature protection
• External synchronizable up to 12MHz
• Pb-free plus anneal available (RoHS compliant)
The ISL8010 is available in the 10 Ld MSOP package,
2
making the entire converter occupy less than 0.18in of PCB
area with components on one side only. The 10 Ld MSOP
package is specified for operation over the full -40°C to
+85°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.
