40W 18V Demoboard using ICE3B2065P on board
Abstract
This application note is a description for a 40W switching mode power supply evaluation board designed in a
TM1
typical off-line flyback converter topology that utilizes the ICE3B2065P F3 CoolSET
. The application
operates in discontinuous conduction mode and is especially suitable for applications such as an AC/DC
power supply for LCD monitor, DVD player and set-top box, adapter for printer and notebook computer as
well as auxiliary power supply for higher power system. Designed based on the proven technology of F2

CoolSET
ICE2xxxxx, the F3 CoolSET
provides Active Burst Mode to reach the lowest Standby Power
Requirement at less than 100mW during no load condition. In Active Burst Mode the ripple of the output can
also be reduced to less than 1%. Furthermore, an adjustable Blanking Window by varying the value of Soft
Start capacitor is being offered to support applications which needs surge power for a limited period of time
(e.g. switching on capacitive loads).
