Monolithic 600mA Step-Down Regulator

with Low Quiescent Current

The EL7530 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 EL7530 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 shut-down current, short-circuit

protection, and over-temperature protection.

The EL7530 is available in the 10-pin MSOP package,

making the the entire converter occupy less than 0.18n

PCB area with components on one side only. The 10-pin

MSOP package is specified for operation over the full -40°C

to +85°C temperature range.

Ordering Information

NOTE: Intersil Pb-free 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-020C.
