Our customer is developing OBC/DCDC platform. I see both UCC28C45-Q1 PWM controller and LM3481-Q1 or LM5155-Q1 flyback can be used…
Part Number: UCC28C45-Q1 Other Parts Discussed in Thread: UCC28C45 , TL431 Dear TI,
I am currently prototyping a flyback converter design using an UCC28C45QDRQ1 controller in voltage mode at a switching frequency of 500kHz. I noticed the converter works in…
Part Number: UCC28C45-Q1 Hello,
I have just got doubt whether can I use Active clamp topology in 800W to 1KW application?
All the literature says Active clamp forward can be used up to 500W.
Lets discuss in the forum what are consequences (pros & cons…
Ben,
thanks.
Then what caused the difference of recommended operating temperature between UCC28C45 and UCC28C45-Q1, regarding both can endure 150C maximum junction temperature.
Is it guaranteed through test for Q version device?
Part Number: UCC28C45-Q1 Other Parts Discussed in Thread: TINA-TI I am trying to make an active clamp forward for a 75v-135v dc input and 12v/20A output using a ucc28c45-q1 grade controller.
When i try simulating the circuit on TINA-TI, i get an error…
Hello,
TI does not have a single controller for driving a two switch forwarded with SRs.
The UCC28C42-Q1 is a popular device for two switch forward converters. You can use a gate drive transform for the high side FET and another one for the SR FETs…
