General Description
CR622X combines a dedicated current mode PWM
controller with a high voltage power MOSFET. It is
optimized for high performance, low standby power,
and cost effective off-line flyback converter
applications in sub 24W range.
CR622X offers complete protection coverage with
automatic self-recovery feature including
Cycle-by-Cycle current limiting (OCP), over load
protection (OLP), VDD over voltage clamp and
under voltage lockout (UVLO). Excellent EMI
performance is achieved with frequency shuffling
technique together with soft switching control at he
totem pole gate drive output.
CR622X is offered in DIP-8L & SOP-8L package.
