QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 559

SYNCHRONOUS BOOST CONVERTER WITH OUTPUT DISCONNECT

LTC3429

DESCRIPTION

Demonstration circuit 559 is a high efficiency synchro-

nous boost DC/DC converter with output disconnect,

inrush current limiting and soft-start functions featuring

the LTC3429. The board is capable of supplying 90mA

from a single AA cell input or 250mA from a 2-cell input

with a 3.3V output. The input range is from 1V to 3.3V.

DC559 version A uses the LTC3429; version B uses the

LTC3429B. The LTC3429 shifts automatically to power

saving Burst Mode operation at light loads; whereas the

LTC3429B operates at a fixed frequency for all loads with

minimum output voltage ripple.

A switching frequency of 500KHz allows up to 95% effi-

ciency with a tiny solution footprint. Typical applications

include MP3 players, GPS receivers, digital cameras,

PDAs, LCD bias supplies and wireless handsets.

Design files for this circuit board are available. Call

the LTC factory.

QUICK START PROCEDURE

Demonstration circuit 559 is easy to set up to evaluate

the performance of the LTC3429. Refer to Figure 1 for

proper measurement equipment setup and follow the

procedure below:

measuring the input or output voltage rip-

ple, care must be taken to avoid a long ground lead on

the oscilloscope probe. Measure the input or output

voltage ripple by touching the probe tip directly across

the Vin or Vout and GND terminals. See Figure 2 for

proper scope probe technique.

NOTE:

When

Place the jumper in the following position:

JP1

With power off, connect the input power supply to Vin

and GND. Connect the load to Vout and GND. Set ini-

tial load = 0A (no load).

Turn on the power at the input.

NOTE:

Make

sure that the input voltage does not ex-

ceed 4.4V.
