EL7531
Monolithic 1A Step-Down Regulator with
Low Quiescent Current
The EL7531 is a synchronous, integrated FET 1A 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 EL7531 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 EL7531 is available in the 10-pin MSOP package,
making the entire converter occupy less than 0.15 in
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.
