ISL8010

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

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,

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.
