3 Description

The LMR33610 SIMPLE SWITCHER® regulator is

an easy-to-use, synchronous, step-down DC/DC

converter that delivers best-in-class efficiency for

rugged industrial applications. The LMR33610 drives

up to 1 A of load current from an input of up

to 36 V. The LMR33610 provides high light-load

efficiency and output accuracy. Features such as a

power-good flag and precision enable provide both

flexible and easy-to-use solutions for a wide range

of applications. The LMR33610 automatically folds

back frequency at light load to improve efficiency.

Protection features include thermal shutdown, input

undervoltage lockout, cycle-by-cycle current limit, and

hiccup short-circuit protection. Integration and internal

compensation eliminates many external components

and provides a pinout designed for a simple PCB

layout. The feature set of the device is designed

to simplify implementation for a wide range of end

equipment. The LMR33610 is pin-to-pin compatible

with the LMR33620, LMR33630, LMR33640 (36 V, 2

A,3 A, 4 A), LMR36510 (65 V, 1 A), and LMR36520

(65 V, 2 A), completing the family of scalable SIMPLE

SWITCHER power supplies. This minimizes the cost

and effort associated with board layout modifications.

The LMR33610 is available in an 8-pin HSOIC

package.
