QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 793

SINGLE OUTPUT, DUAL PHASE SYNCHRONOUS BUCK CONVERTER

LTC3709

DESCRIPTION

Demonstration circuit 793 is a single output, dual phase

synchronous buck converter featuring the LTC3709EUH.

The output voltage is 1.5V with a load rating of 30A and

the input voltage range is 7V to 24V.

The combination of dual phase operation and valley cur-

rent mode control allows the converter to have a fast

load step recovery. A simple on-board dynamic load step

circuit is provided for load step testing. Other features

highlighted by demonstration circuit 793 include no

SENSE

™ operation, high efficiency at both heavy and light

loads and rail tracking. Typical applications include desk-

top and notebook computers, FPGA systems, DSPs and

servers.

An LT3010EMS8E-5 (5V / 50mA LDO) provides current

for the LTC3709EUH’s internal logic and gate drive cir-

cuitry. The 5V bias can also be supplied externally. For

input voltages less than 5V, the board contains a foot-

print for an LT1613 boost converter with a 5V output.

NOTE:

an external bias voltage is applied it needs to be

between 4.2V and 7.0V.

Design files for this circuit board are available. Call

the LTC factory.

QUICK START PROCEDURE

Demonstration circuit 793 is easy to set up to evaluate

the performance of the LTC3709EUH. Refer to Figure 1

for proper measurement equipment setup and follow the

procedure below:

With power off, connect the input power supply to Vin

and GND.

Turn on the power at the input and set the input volt-

age to 12V.

Check for the proper output voltage. V

OUT

should

range from 1.47V to 1.53V.

Apply 30A load and re-check the regulation.
