CURRENT MODE PWM+PFM CONTROLLER
DESCRIPTION
SD4872X 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.
SD4872X offers complete protection functions including cycle-
by-cycle over current protection, over load protection, over
voltage and under voltage protections for VDD voltage, etc.
Excellent EMI performance is achieved with frequency...
