EL7530
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
IN
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
2
of
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.

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.
