  • TIDA-01505: TIDA-01505

    Part Number: TIDA-01505 Other Parts Discussed in Thread: UCC28C42 , UCC28C43 Hello, In this reference design, the flyback controller being used is UCC28C43. Due to the part shortage issue, may I ask if I use UCC28C42 instead, shall I modify the circuit…

  • TIDA-01505: Issue when testing EVM

    Part Number: TIDA-01505 Hello, Team we connect HV_DC (40V) / LV_DC (J19, +20V/-5V), we found HV_DC is pull to 20V by LV_DC, after we remove Q10, it when back to normal, any thought of that ?

  • TIDA-01505: Transformer calculation for CCM

    Part Number: TIDA-01505 The transformer inductance is 1.5mH for this reference design. What is the assumed ripple factor for CCM mode? Also I tried using the Flybuck, Flyback excel file. The inductance i got from there was lower.
