SDC SDC4569A
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. The Tgate drive output is clamped to maximum 12V to protect CONFIDENthe power MOSFET.GENERAL DESCRIPTION
FEATURES
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. DSDC4569A offers complete protection coverage with Lautomatic self-recovery feature including cycle-by-cycle current limiting (OCP), over load protection (OLP), VDD IAover voltage clamp and under voltage lockout (UVLO).● Frequency shuffling technology for impro
