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
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 Ld MSOP package,
making the entire converter occupy less than 0.18n
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.
Ordering Information
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.
