Description
The CoolSET®-F3R jitter series (ICE3BRxx65J) is the
latest version of CoolSET®-F3. It targets for the Off-Line
battery adapters and low cost SMPS for lower power
range such as application for DVD R/W, DVD Combi, Blue
ray DVD player, set top box, etc. Besides inherited the
outstanding performance of the CoolSET®-F3 in the
BiCMOS technology, active burst mode, auto-restart
protection, propagation delay compensation, etc.,
CoolSET®-F3R series has some new features such as
built-in soft start time, built-in blanking window, built-in
frequency jitter, soft gate driving, etc. In case a longer
blanking time is needed for high load application, a simple
addition of capacitor to BA pin can serve the purpose.
Furthermore, an external auto-restart enable feature can
provide extra protection when there is a need of
immediate stop of power switching.
