SDC4566
General Description
Features
SDC4566 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 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.
DSDC4566 offers complete protection coverage with
Lautomatic self-recovery feature including cycle-by-cycle
current limiting (OCP), over load protection (OLP), VCC
IAover voltage clamp and under voltage lockout (UVLO). The
Tgate drive output is clamped to maximum 14V to protect
CONFIDENthe power MOSFET.
Frequency shuffling technology for improved emc
performance
Audio noise free operation
Extended burst mode control for improved efficiency
and minimum standby power design
Internal synchronized slope compensation
Low VCC startup current and low operating current
Leading edge blanking on current sense input
Good protection coverage with auto self-recovery
(UVLO/OVP/ OCP/OLP/OTP)
FB/CS open loop protection
Secondary Rectifier Short Protection
Package: SOT-23-6
Applications
Battery charger
Power adapter
Set-top box power supplies
