DEMO CIRCUIT 1323

LT3686

QUICK START GUIDE

LT3686EDD

37V, 1.2A, Buck Regulator

DESCRIPTION

Demo circuit 1323 is a current-mode PWM step-down

DC/DC regulator with an internal 1.2A power switch fea-

turing the LT3686. The demo circuit is designed for 3.3V

output from a 5V to 37V input. The wide input range of

the LT3686 allows a variety of input sources. The typical

sources are automotive batteries and industrial supplies.

Its high maximum frequency allows the use of tiny in-

ductors and capacitors. Operating frequency above the

AM band avoids interfering with radio reception, making

the LT3686 particularly suitable for automotive applica-

tions.

Cycle by cycle current limit and DA current sense provide

the protection against shorted outputs. Soft-start and

frequency foldback eliminate input current surge during

startup. An optional internal regulated active load at the

output via the BD pin keeps the LT3686 at full switching

frequency at light loads, resulting in low, predictable out-

put ripple above the audio and AM bands. Internal com-

pensation and an internal boost diode reduce external

component count.

The LT3686 datasheet gives a complete description of

the part, operation and application information. The data-

sheet must be read in conjunction with this quick start

guide for Demo Circuit 1323.

LT3686 is available in 3mmx3mm DFN package.

Design files for this circuit board are available. Call
