Description
RM622X combines a dedicated current mode PWM controller with a high volt age power MOSFET .
It is o ptimized for high performance,low standby power ,and cost effective of f-line flyback converte r applications in sub 20W range.
Features
- Power on soft start reducing MOSFET Vds stress.
- Frequency shuffling for EMI.
- Extended B urst Mode control fo r improved e fficiency and minimum standby power design.
- Audio noise free operation.
- Fixed 50Khz switching frequency.
- Internal synchronized slop compensation.
- Low VDD st art-up curre nt and low operationg current.
- LEB and current sense input.
- Good protec tion coverag e with auto self-recovery.
- VDD over volt age clamp and under voltage lo.
