QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 913

POLYPHASE 3-OUTPUT STEP-DOWN SUPPLY WITH TRACKING

LTC3773EUHF

DESCRIPTION

Demonstration circuit 913 is a high efficiency and

high density supply featuring the 3-output, 3-phase

synchronous buck regulator LTC3773. The input

voltage range of the demo board is designed for 4.5V

to 13.5V, though the LTC3773 controller can take up

to 36V

MAX

Vin. The outputs of this board are

2.5V/15A,1.8V/15A and 1.2V/15A. To minimize input

ripple current and capacitor size, there is 120

phase

clock interleaving among every two phases. The

power up/down tracking of the three output voltages

is programmable. The supply can be synchronized

to an external clock signal.

The critical power components are on the top side of

the PC board and are within a 1.7” x 1.7” “drop-in”

layout area. The small signal components and IC are

on the bottom side of the PC board within a 1” x 1”

board area. The LTC3773EUHF regulator IC is in a

small 5mm x 7mm QFN package with exposed ther-

mal pad for low thermal impedance. An optional 5V

bias supply is stuffed on the board to power the

LTC3773.

Design files for this circuit board are available.
