Current Mode PWM Power Switch
Datasheet
SDC4109
General Description
Features
SDC4109 combines a dedicated current mode PWM
Tcontroller with a high voltage power MOSFET. It is
optimized for high performance, low standby power, and
Ncost effective off-line flyback converter applications in sub
E27W range.
MSDC4109 offers Complete protection coverage with
automatic self-recovery feature including cycle-by-cycle
Ucurrent limiting (OCP), over load protection (OLP), VDD
Cover voltage clamp and under voltage lockout (UVLO).
Excellent EMI performance is achieved with frequency
Oshuffling technique, together with soft switching control
Dat the totem pole gate drive output. The tone energy at
below 22kHz is minimized in the design and audio noise is
CONFIDENTIALeliminated during operation
Power on soft start reducing MOSFET VDS stress
Frequency shuffling for EMI
Extended burst mode control for improved
efficiency and minimum standby power design
Audio noise free operation
Fixed 50kHz switching frequency
Internal synchronized slope compensation
Low VDD startup current and low operating current
Leading edge blanking on current sense input
Good protection coverage with auto self-recovery:
VDD over voltage clamp and under voltage lockout
with hysteresis (UVLO)
Line input compensated cycle-by-cycle over-current
threshold setting for constant output power limiting
over universal input voltage range
Over load protection (OLP)
Over voltage protection(OVP)
Applications
Battery charger
PDA power supplies
Digital cameras and camcorder adaptor
VCR, SVR, STB, DVD&DVCD player SMPS
Set-top box power
Auxiliary power supply for PC and server
Open-frame SMPS
