QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 412

LOW INPUT VOLTAGE, HIGH CURRENT BUCK CONTROLLER

LTC3713

DESCRIPTION

Demonstration Circuit 412 is a synchronous step-down

regulator using the LTC3713 No R

SENSE

switching

regulator controller. It can operate at low input voltage

down to 1.7V and supply up to 10A of output current.

Higher current can be obtained by changing external

components. DC412 provides a low input buck regulator

to supply lower voltages for microprocessors, DSPs,

and bus termination applications. An onboard boost

converter generates the gate-drive voltage for the exter-

nal power MOSFETs and allows the use of standard 5V

logic-level N-Channel MOSFETs.

Design files for this

circuit board are available. Call the LTC factory.

JP1 sets the operation mode. The lower position selects

Forced Continuous synchronous operation, which mini-

mizes noise and RF interference, and also allows the

output to sink current for applications like bus termina-

tors. RSNS1, RSNS2, R7, R8 and D1 help in modifiying

the design for symmetric current limit. Please refer to

the “Applications Requiring Symmetric Current Limit”

section in the LTC3713 data sheet for details.

*Higher output current can be achieved by using higher current rating

inductor and adding parallel MOSFETs (M3, M4).

QUICK START PROCEDURE

Refer to Figure 1 for proper measurement equipment

setup and follow the procedure below:

Connect the input power supply to the VIN and GND

Shunt JP2 and JP4 for operation. V

OUT

goes to 0V

terminals.

NOTE:

Do not increase V

over 6V (If higher input

with either JP2 or JP4 open. If JP3 is connected,

overcurrent latchoff is disabled. Refer to the “Applica-

tions Information” section in the LTC3713 data sheet

for details.

Set the FCB Jumper JP1 to the lower position to force

voltage is desired, use higher voltage rating input

capacitors. If the input voltage is always higher than

4V, you probably want to consider using demo circuit

DC378, which features the LTC1778.)

Connect the desired load between the VOUT and GND

continuous synchronous operation at light loads; or

to the upper position to enable discontinuous mode

operation at light loads.

When measuring the output ripple, see Figure 2 for

terminals. Soldered wires should be used to achieve

optimum performance.

the proper technique using the scope probe.
