CR622X combines a dedicated current mode PWM controller with a high voltage power MOSFET.

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.
