General Description
CR6228 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 27W range.
Key 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 of 0.77V. Every restart up is followed by a soft start. Startup Current and Start up Control Startup current of CR6228 is designed to be very low so that VDD could be charged up above UVLO threshold level and device starts up quickly. A.
