Monolithic 1A Step-Down Regulator

The EL7536 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

divider.

The EL7536 features PWM mode control. The operating

frequency is typically 1.4MHz. Additional features include a

100ms Power-On-Reset output, <1µA shut-down current,

short-circuit protection, and over-temperature protection.

The EL7536 is available in the 10 Ld MSOP package,

making the entire converter occupy less than 0.15in

area with components on one side only. Both packages are

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.
