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

Key Features

Soft Start CR622X features an internal 4 ms soft start to soften the electrical stress occurring in the power supply during startup. It is activated during the power on sequence. As soon as VDD reaches UVLO(OFF), the peak current is gradually increased from nearly zero to the maximum level. Every restart up is followed by a soft start. Frequency shuffling for EMI improvement The frequency shuffling (switching frequency modulation) is implemented in CR622X. The oscillation frequency is modulated.
