Design Note DN 2013-01
V1.0 January 2013
STEP 15: Other Considerations
A.
Input Diode Bridge Voltage and Current Rating
B.
Current Sense Resistor, Rsense
C. VCC Capacitor:
Chose forward current rating >1.4A
Commonly used is 600V rated bridge
rectifier
Use 1.3 ohm 0.25W x 2 in
parallel
D. Feedback Loop Compensation: Below shows the complete Flyback schematic including values and
implementation of the feedback circuit.
