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 V

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 0.18in

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.
