QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 921

MICROPOWER SYNCHRONOUS BUCK-BOOST CONVERTER

LTC3532

DESCRIPTION

Demonstration circuit 921 is a micropower synchro-

nous buck-boost converter based on the LTC3532

monolithic buck-boost regulator. The DC921 has an

input voltage range of 2.4 V to 5.5V and an output of

3.3V @ 300mA. The converter can work under manual

or programmable automatic burst mode, providing

high conversion efficiency over a wide range of load

currents. The LTC3532 comes in a 10 lead 3×3 DFN

package. These features make the DC921 demo board

an ideal circuit for use in Li-Ion battery-powered,

hand-held applications.

NOTE

Some of the optional components should be stuffed for

Vin > 4.5V as discussed in the Datasheet

Design files for this circuit board are available. Call

the LTC factory.

QUICK START PROCEDURE

Refer to Figure 1 for proper measurement equipment

setup and follow the procedure below:

Set Power Supply anywhere between 2.4V to 5.5V.

The Load can be set from 0 – 300mA.

Start with Load set to 0A.
