Monolithic 600mA Step-Down Regulator
with Low Quiescent Current
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
accommodates supplies of 3.3V, 5V, or a Li-Ion battery
source. The output can be externally set from 0.8V to VIN
with a resistive divider.
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.
The ISL8010 is available in the 10 Ld MSOP package,
making the entire converter occupy less than 0.18in2 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.

NOTES:
1. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special
Pb-free material sets, molding compounds/die attach materials,
and 100% matte tin plate plus anneal (e3 termination finish,
which is 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.
3. For Moisture Sensitivity Level (MSL), please see device
information page for ISL8010. For more information on MSL
please see techbrief TB363.
