CURRENT MODE PWM CONTROLLER
DESCRIPTION
SD4871 is a current mode PWM controller IC for high
performance, low standby power offline flyback converter
application.
In no load or light load condition, the IC operates in Light Load
Mode to reduce switching loss and improve efficiency.
Large startup resistor could be used in the startup circuit to
minimize the standby current because of low startup current.
SD4871 offers complete protection functions including cycle-bycycle over current protection, over load protection, over voltage
SOT-23-6L
and under voltage protections for VDD voltage, etc.
Excellent EMI performance is achieved with frequency shuffling
technique a...
