1.4A, 500kHz Step-Down

Switching Regulator

FEATURES

DESCRIPTIO

The LT^®1936 is a current mode PWM step-down DC/DC

converter with an internal 1.9A power switch, packaged in

a tiny, thermally enhanced 8-lead MSOP. The wide input

range of 3.6V to 36V makes the LT1936 suitable for

regulating power from a wide variety of sources, including

automotive batteries, 24V industrial supplies and unregu-

lated wall adapters. Its high operating frequency allows

the use of small, low cost inductors and ceramic capaci-

tors, resulting in low, predictable output ripple.

■

Wide Input Range: 3.6V to 36V

■

Short-Circuit Protected Over Full Input Range

■

1.9A Guaranteed Minimum Switch Current

■

5V at 1.4A from 10V to 36V Input

■

3.3V at 1.4A from 7V to 36V Input

■

5V at 1.2A from 6.3V to 36V Input

■

3.3V at 1.2A from 4.5V to 36V Input

■

Output Adjustable Down to 1.20V

■

500kHz Fixed Frequency Operation

■

Soft-Start

Cycle-by-cycle current limit, frequency foldback and ther-

malshutdownprovideprotectionagainstshortedoutputs,

and soft-start eliminates input current surge during start-

up. Transient response can be optimized by using external

compensation components, or board space can be mini-

mized by using internal compensation. The low current
