Part Number: UCC3813-4 Hi Expert,
The customer reported the UCC3813-4 output pin being short to Gnd pin from end customer site.
They can see 19 units being damage during 4000 units build.
Can you help to comment the schematic and captured waveforms as…
Part Number: UCC3813-4 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Hi,
Why does Startup and Steady State exist for TINA-TI Reference Design of UCC 3814 and other AC / DC cotrolars?
Thanks
Part Number: UCC3804 Other Parts Discussed in Thread: UCC3813-4 , UCC3800 Hi
I see the specifications UCC3804 and UCC3813-4 are similar, but the price are different. What is the difference between these two?
thank you.
Part Number: UCC3813-3 I am using the UCC3813-3 in a flyback to generate 800 V from 48 V.
If a load of 25 mA is connected to the output voltage the duty cycle is 40 % and the transformer heats up to 50 °C.
If no load is connected the output voltage…

Part Number: UCC3813-1 Other Parts Discussed in Thread: UCD3138 , , UCD3138HSFBEVM-029 I am working with a UCD3138 hard switching full bridge evaluation module (UCD3138HSFBEVM-029). It uses a UCC3813-1 for the 3 housekeeping supply rails. Schematic available…
Dear Peter
Thanks. Please find attached excel sheet.
In this Lm and OP Capacitor calculation is there as per application note given in datasheet.
