RM622X - PWM controller

General 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 lo.

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. RM622X of fers co mplete protection coverage w ith automatic self-recovery feature inclu ding C ycle-by-Cycle current limiting,over load pr otection,VDD over voltage clamp and under volt age lockout. Excellent EMI performance is achieved with freque ncy shuf fling technique together with sof t switching control at the totem pole gate drive output. The tone energy at below 20khz is minimized in the design and audio nosie is eliminated during ope ration.RM622X is offered
