QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 1193

TRIPLE DC/DC CONVERTER

LTC3545/-1

DESCRIPTION

Demonstration circuit 1193 is a triple output regulator

consisting of three constant-frequency step-down

converters integrated into LTC3545/-1. DC1193 has

an input voltage range of 2.25V to 5.5V, with regula-

tors capable of delivering 800mA of load current on

each output. The three regulators operate independ-

ently with individual RUN pins and enter pulse skip-

ping mode at low loads for reducing output ripple. In

shutdown, the DC1193 draws less than 1uA total. The

DC1193 is a very efficient circuit with efficiency read-

ing above 90%. The LTC3545 comes in a 16-pin QFN

package, which has an exposed pad on the bottom-

side of the IC for better thermal performance. High

operating frequency of 2.25MHz allows exclusive use

of the small size, low profile surface mount compo-

nents. These features plus internal compensation cir-

cuits, make the DC1193 demo board an ideal circuit

for use in battery-powered, hand-held applications.

DC1193A-A is a demoboard for LTC3545 and

DC1193A-B is a demoboard for LCT3545-1.

Design files for this circuit board are available. Call

the LTC factory.
