Part Number: UCC28250 Other Parts Discussed in Thread: UCC25600 , Tool/software: I am working on a new project that involves designing a full-bridge LLC resonant converter with an AC RMS input and a 12V/5V DC output with a target power rating of around…
Part Number: UCC28250 Tool/software: Hi team,
Do we have PSPICE transient model for UCC28250? Or any similar pin compatible device and function device have PSPICE transient model?
Thanks

Part Number: UCC28250 Tool/software: Hi,
Specification:
INPUT: 30 to 130V DC OUTPUT: 13.8V / 30A Reference Design: UCC28250EVM-501
We have developed our own PCB based on the required form factor and have started testing. It has been working fine…
Part Number: UCC28250 Other Parts Discussed in Thread: UCC28251 , UCC28C51 Dear support team, We are using the UCC28250 as a PWM controller with a switching frequency (fsw) of 100kHz set by a 147kOhm RT resistor and we would like to decrease this switching…
Part Number: UCC28250 Hı team i did not understand some things in pre biased operation
For example
1-) Is it necessary to apply voltage to the pre bias outputs along with the input voltage to start the controller? Cant the controller work without…
Part Number: UCC28250 Hi team,
it seems that we met a bug on using our EN_pin to enable and disable the device:
it would work well if we put over 2.25V on EN_pin to enable the device;
but if we put 2.2v on En_pin, it seems that the device would…
Part Number: UCC28250 Other Parts Discussed in Thread: LM5046 , UCC28951 Dear Team,
Does this chip can be used in resonant mode ? If yes, do you have any technical articles about it ? Since as far as I know, for resonant mode i would need phase shifted…
Part Number: UCC28250 Hello,
I am developing an ac/dc converter using UCC28250.
It is used as secondary side control, and the topology applies full bridge.
I am developing 3kW, and even if I load only 0.1A,
the heat rises close to 70 degrees in…
Part Number: UCC28250 Other Parts Discussed in Thread: UC3842 , UCC28251 Dear Support Team,
We use the UCC28250 as a PWM controller for an isolated full-bridge 44V -> 12V. The controller is configured for primary side control with voltage feedforward…
Part Number: UCC28250 Hello
We developing a rectifier that varies the output voltage from 30V to 200V.
It is currently configured with secondary side control.
In this case, I am curious about how to set the VSENSE Pin.
The output is varied by…
