Hello to everyone,
Currently I'm designing LED drvr cct. The specs for my design are as follow:
*********************************
Vin = 100 - 240 V
Vo = 20
Po = 100
efficiency = 80%
duty cycle = 0.45
flyback transformer, isolated and DCM
using TL5001 and optocoupler
*********************************
Attached is my circuit for the design. I need guidance from the expert or anyone on how to implement the PWM using TL5001 with opto-coupler. Is this design okay? Is the value of capacitors and resistors correct? I designing the TL5001 based on the example application using TL5001 but the example only for step down converter and low voltage. I also need someone to check my feedback design.
Sorry for my bad English.
Thank you for all your help.
