Part Number: UCC25600-DESIGN-CALC Other Parts Discussed in Thread: UCC25600 I am reading the UCC25600 datasheet. And I came across the designing of parameters for Overcurrent pin. I am really not getting how to design the values for resistor and capacitor…
Hello Ravi
I am sorry I am not a heat-sink design expert. Please refer https://www.ti.com/tool/PMP10804 for the heat-sink size of the MOSFETs and the diode.

Part Number: FLYBUCK-FLYBACK-DESIGN-CALC Other Parts Discussed in Thread: LM5155 , LM5156 Hello, We are wondering if there is any suitable controller and circuit or calculator for the design of a flyback topology DC/DC converter that can meet the requirements…
Part Number: LM5069QUICK-CALC Other Parts Discussed in Thread: LM5069 Dear team,
I'm using the LM5069 Design Calculator with FET Recommendation for SOA calculation
However Some of the green cells in the calculator is invalid.
1. can't set the load…
Part Number: TPS552882 While performing WCCA, I've noticed that the calculated inductor(9.6uH-> Even at nominal values) is far less than the recommended value from both webench & excel calculator(max.2.5uH). Added the webench report here for…
Hi Ravindran,
Thank you for designing with the LM5185. I reviewed your calculator file, it is looks okay. Some suggestions:
DCLAMP choose 36V, so you can use 100V MOSFETs.
RFB should be 255k, not 284k.
Reserve the option of using external SS by adding…
Part Number: UCC28711 Tool/software: Hello! I'm curious about what elements need to be changed and if there are any reference materials available if you want to increase the capacity to 100W in the topology of a 400- to 690-V AC Input 50-W Flyback Isolated…
Part Number: LM5022
Hi TI experts,
For LM5022 based flyback design, we measured there is about 20ms delay from Input ramps up to Vout starts ramping.
Can i know why there is a delay?
How can we reduce the delay?
Thanks.
Input and output waveform:
