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
TM
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.
