Description
650V avalanche rugged CoolMOS® with built-in
The CoolSET®-F3R FullPak is the enhanced version of
CoolSET®-F3 and targets for the Off-Line Adapters and
high power range SMPS in DVD R/W, DVD Combi, set top
box, etc. It has a wide Vcc range to 25V by adopting the
BiCMOS technology. With the merit of Active Burst Mode, it
can achieve the lowest Standby Power Requirements
(<100mW) at no load and Vin = 270VAC. Since the
controller is always active during the Active Burst Mode, it
is an immediate response on load jumps and leads to <1%
voltage ripple voltage at output. In case of protection for
Overtemperature, Overvoltage, Open loop and Overload
conditions, it would enter Auto Restart Mode. Thanks for the
internal precise peak current limitation, it can provide
accurate information to optimize the dimension of the
transformer and the output diode. The built-in blanking
window can provide sufficient buffer time before entering
the Auto Restart Mode. In case of longer blanking time, a
simply addition of capacitor to BA pin can serve the
purpose. Furthermore, the built-in frequency jitter function
can effectively reduce the EMI noise and further reduce the
scale of input filter. The component counts can further be
reduced with the various built-in functions such as soft start,
blanking time and frequency jitter.
