Current Mode PWM Controller
Datasheet
SDC4563
General Description
Features
SDC4563 is a highly integrated current mode PWM control
TIC optimized for high performance, low standby power
and cost effective offline flyback converter applications in
Nsub 30W range. EThe internal slope compensation improves system large Msignal stability and reduces the possible subharmonic
oscillation at high PWM duty cycle output. Leading-edge
Ublanking on current sense(CS) input removes the signal Cglitch due to snubber circuit diode reverse recovery and
thus greatly reduces the external component count and
Osystem cost in the design.
