Part Number: UCC28750 Tool/software: Hello,
I recently used WEBENCH to derive a circuit for an isolated flyback using the UCC2875 IC. I want to simulate the circuit using the SIMPLIS since the model is on the TI website. Unfortunately, I keep getting…
Part Number: UCC28750 Tool/software: As shown in the attached circuit diagram, I'm planning to use it with a bulk voltage between 120Vdc and 392Vdc. Is there a problem? The bulk voltage will be applied to VDD for start-up, but this will exceed the VDD…

Part Number: UCC28750 Hi,
We're using the UCC28750 2 in our design, we want to implement an OVP for 420VDC. We've set a resistor divider from the Bulk Capacitors to the FLT pin to trip at 4.1V FLT pin voltage.
The OVP doesn't occur at the defined…
Part Number: UCC28750 Tool/software: Inquiry on UCC28750 for Flyback Converter Design
Dear TI,
I am currently designing a flyback converter and require assistance. My design parameters are an input voltage of 70-120V DC and an output voltage of 12V…
Part Number: UCC28750 Hi I am working on an offline flyback design using the UCC287505. The supply has two outputs: 12 V / 0.5 A and 3.3 V / 0.5 A (3.3 V generated from the 5 V secondary through an LDO). The AUX winding is designed to give 20V for VDD…
Part Number: UCC28750
Tool/software:
I am using UCC287506 for 36W Flyback power supply, 2 outputs are: 12V power output for fan and 14V output for light load peripheral. with an auxiliary coil of 21V to power the UCC28750 IC.
When I experimented…
