Part Number: UCC28C56H-Q1 Other Parts Discussed in Thread: UCC28C56EVM-066 I am currently working on designing a circuit for operating an LED strip, powered by a battery with a cutoff voltage of 55V and a maximum voltage of 150V. My goal is to step down…
Part Number: UCC28C56H-Q1 Other Parts Discussed in Thread: UCC28C56H Hi Team,
I can see in the webench ckt for the UCC28C56H PSR, the VDD and FB are connected at the same node and not separated by the diode. could you pls explain more how does this…
Part Number: UCC28C56H-Q1 Other Parts Discussed in Thread: UCC28C56EVM-066 I was Testing UCC28C56EVM-066 Evaluation board for my project but while testing PWM IC gone bad. So I need sample parts of UCC28C56H-Q1 immediately to resume my testing.

Could I have your support to explain how HV startup circuit work ? Below circuit is from UCC28C5H EVM, customer want to know how this circuit work and how to calculate this circuit 's parameters.
Part Number: UCC28C56H-Q1 Dear Team
could you pls help with max IDD required for the IC for the below condition?
Fsw = 110kHz
Qg = 36nC
As per our calculations:
IDD = IOUT+Isupply
IDD = 4mA + Isupply
Isupply i can see in the datasheet…

Hello,
what is the exact purpose of R8 and D10 in UCC28C56EVM-066?
I know that D10 is there for overvoltage protection. If Vout is above 18V it will be conducting…
Part Number: UCC28C56H-Q1 Other Parts Discussed in Thread: UCC28C56EVM-066 , Questions about UCC28C56EVM-066, (doc bumber sluucn1c)
1. Q1, Q2 form HV startup for VDD, but zener D5 to Q2's gate, can not be breakup to generate a voltage of 25V. so what…
Part Number: UCC28C56H-Q1 Other Parts Discussed in Thread: UCC28C56EVM-066 HI Team, I have two question about UCC28C56EVM-066 board: 1) In the EVM, the 15Vdc Vout start form 40V of HV_IN power supply. Is possible to modify the EVM for start Vout (15Vdc…
Part Number: UCC28C56H-Q1 Hello TI.
When unloaded, we have around 95V and when fully loaded we have 62V. Is it possible to improve this somehow? Maybe Rfbu is too high? How can this be troubleshooted?
Attached transformer datasheet, do you think it…
Thanks. can i also use the calculation from the datasheet of UCC28C56H-Q1 (automotive version)? because in the datasheet of UCC28C56H, it explains mainly about the offline application and not the high voltage inputs. Please confirm
