DEMO MANUAL DC140

DESIGN-READY SWITCHERS

LTC1436-PLL 2-Output

Synchronous Buck Converter

with Versatile Frequency Controller

DESCRIPTIO

Demonstration circuit DC140 is a 2-output, general pur-

pose evaluation platform intended to demonstrate the

many functions of the LTC

1436-PLL and to make it easy

to implement circuit changes. The switching frequency of

the LTC1436-PLL can be synchronized to an external

clock frequency or modulated to reduce EMI by decreas-

ing the average power of the switching harmonics. The

high efficiency, constant-frequency advantages of the

Adaptive Power

output stage can be observed under

light load conditions. The enable and soft start features of

the LTC1436-PLL can also be observed, along with a

power-on reset (POR) signal for the main output.

DC140 is intended for users with noise-sensitive applica-

tions where conducted and radiated emissions are impor-

tant design considerations. These applications include

radio, cell-phone and other wireless communication prod-

ucts. Two versions of DC140 are available; they differ only

in the magnitude of the second output voltage. Both

versions provide 5V at 3A on the main output. The second

output is derived from the main 5V output and postregulated

by an internal auxiliary linear regulator. Version A pro-

vides a second output voltage of 3.3V at 0.1A, whereas

version B provides a second output of 12V at 0.1A.
