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.
