Description
Connected to the flyback winding. The current on this pin is sensed and used to turn on the Synchronous
Rectification MOSFET (SRFET). This pin is also used to sense the zero crossing of the MOSFET current
either using the R DS(on) of the SRFET or using an external current sense resistor connected between
drain of the SRFET and the flyback winding.
Input pin for direct turn ? off of the MOSFET. Typically connected to a signal from primary controller (for
CCM mode) or a signal derived from the transformer (for QR mode). Has very short propagation delay to
output (<50 ns).
Feedback compensation pin for the TL431 shunt regulator. Has the capability to sinking 10 ma of opto
current.
Output voltage feedback through resistive divider connected to this pin. Regulated at 1.28 V (option B) or
2.55 V (option A).
A resistive divider between the power supply output and ground with the center point tied to the D LYADJ
input pin allows for independent adjustment of the minimum t on and t off delay time. The maximum extern-
al capacitance from this pin to ground is 25 pF.
Return pin for the controller – connected to the output return.
Drive output for external MOSFET – 2.5 A peak drive capability, internally clamped to 13.5 V (Maximum)
Bias voltage for the controller. Maximum voltage is 28 V.
