DEMO CIRCUIT 927

LT3742

QUICK START GUIDE

LT3742

Dual, 2-Phase Step-Down

Switching Controller

DESCRIPTION

Demonstration circuit 927 is a high

density 5V/4A and 3.3V/4A step down

converter featuring the LT3742. A

500kHz fixed frequency current mode

architecture provides fast transient

response with simple loop compensa-

tion components and cycle-by-cycle

current limiting. An internal step-up

regulator is used to generate the

gate drive voltage, allowing the gate

of the external high side N-channel

MOSFET to be driven to full enhance-

ment for the highly efficient opera-

tion. The dual channels operate 180

out of phase to reduce the input rip-

ple current, minimizing the noise in-

duced on the input supply, and allow-

vidual shutdown and power-good output

for each converter. The LT3742 is

available in a small 4mm x 4mm QFN

package.

The LT3742 datasheet gives a complete

description of the part, operation
