QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 901

MICROPOWER SYNCHRONOUS BUCK-BOOST CONVERTER FOR CDMA AND HSDPA

LTC3444

DESCRIPTION

Demonstration circuit 901A features the LTC3444 and is

a highly efficient, 1.5MHz fixed frequency buck-boost

DC/DC converter. The input voltage can range from 3.1V

to 5.0V and is suitable for Li-Ion or three-cell NiCd/NiMH

battery applications while the output voltage can be set

anywhere from 0.8V to 4.2V by injecting a 0.35V – 2.4V

Control Signal.

The DC901A has been optimized for use in 3G WCDMA

applications. High efficiency is achieved at very low out-

put voltages while component count is minimized. The

board provides the fast transient response required to

slew the RF power amplifier from standby to transmit

and transmit to standby levels. Output overvoltage pro-

tection protects the RF power amplifier.

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:

1.

Start with Load set to 0A.

2.

Set Power Supply 1 to 3.3V and Power Supply 2 to

1V.

3.

The Load can be set from 0 – 400mA.
