QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 1062

DUAL BUCK-BOOST + BUCK SYNCHRONOUS CONVERTERS

LTC3520

DESCRIPTION

Demonstration circuit 1062 is a micropower synchro-

nous buck-boost + buck converter based on the

LTC3520. The DC1062 has an input voltage range of

2.2 V to 5.5V and three output voltages: 3.3V @ up to

1A, 1.8V @ 600mA and 1.5V @ 200mA. The 1.5Vout is

an LDO regulator derived from either the 3.3Vout or

the 1.8Vout. The Buck-Boost + Buck converters can

operate in either low-power burst mode or low-noise

fixed-frequency PWM mode. The switching frequency

is programmed using a single resistor and each of the

output voltages can be independently shutdown. The

LTC3520 comes in a 24 pin 4×4 QFN package. These

features make the DC1062 demo board an ideal circuit

for use in Li-Ion battery-powered, hand-held applica-

tions.

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:

Start with Loads 1, 2 and 3 set to 0A.

Set Power Supply anywhere between 2.2V to 5.5V.

Loads 1, 2 and 3 can be set from 0 – 500mA, 0 –

600mA and 0 – 200mA respectively. Load 1 can be

set up to 1A for Vin > 3V.
