Monolithic 600mA Step-Down Regulator with Low Quiescent Current

DATASHEET

Rev 6.00

October 18, 2010

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
