General Description
Features
SDC4569A is a highly integrated current mode PWM
Tcontrol IC optimized for high performance, low standby
power and cost effective offline flyback converter
Napplications in sub 60W 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.
