Part Number: UCC38C52 Other Parts Discussed in Thread: TL431 I am not able to understand design criteria for opto coupler selection.
1. How resistor connected to emiiter is calculated.
2. What is the selection criteria for selection of CTR of opto…
Part Number: UCC38C52 As per datasheet,
Rstart= 420k ohm, Cvdd= 120uF
Start up time is mentioned as 7 sec. How is that calculated?
With RC time constant formula, it is very high.
I am not able to understand. If somebody could help me out?…
