QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 473

LTC1702A

DESCRIPTION

Demonstration circuit 473A is a high

efficiency dual output synchronous

buck converter using the constant

frequency

LTC1702A

dual

channel

switching controller. It operates

from a 3V to 7V input and generates

1.8V at 5A and 2.5V at 5A. The

LTC1702A operates at 550kHz typical

switching frequency and uses voltage

mode control to switch a pair of N

channel MOSFETs. MOSFET R

DS(ON)

used for short circuit protection.

For operation at 3.3V, the demo board

uses sub-logic level power MOSFETs.

Design files for this circuit board

are available. Call the LTC factory.

HIGH EFFICIENCY DUAL OUTPUT POWER SUPPLY

QUICK START PROCEDURE

Demonstration circuit 473 is easy to

set up to evaluate the performance of

the LTC1702A. Refer to Figure 1 for

proper measurement equipment setup

and follow the procedure below:

NOTE:

Turn on the power at the input.

NOTE:

Make sure the voltage

not exceed 7V at turn on.

will

Check

When measuring the input or

output voltage ripple, 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 termi-

nals. See Figure 2 for proper scope

probe technique.

Vout1 = 1.764V to 1.836V, Vout2 =

2.450V to 2.550V

In case of no output, verify that

the load is not set too high by

temporarily disconnecting the load.

Once outputs are established at the
