RM6222D
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.
Key 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 lockout with hysteresis
