Part Number: UCC28C56H-Q1 Other Parts Discussed in Thread: UCC28C56H , UCC24612 Dear Team,
I am designing Flyback with UCC28C56H-Q1 for the below specs. As you can see the Transient voltage at input side is for 5sec and remaining times the Steady state…
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 connection…
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 it varies with…
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…

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 is…
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 could…
Hi Mike,
I'm looking for Flyback QR+SR for high Efficiency and spec is Low input 28V DC and another design 115VAC to 5V, 3A output.
QR Flyback selected UCC28C56H Q1 and SR planning to use UCC24612. it would be great if you have both combined PSPICE…
Hi Toktam,
Steve is out a couple of days due to thanks giving.
Sorry that you were not able to have webench model. But we do have PSPICE model for UCC28C56 in the product folder ready to download for the single switch flyback option.

Hi Bright,
The best way to isolate power path from the control ground would be to have a star connection at the bulk capacitor. So the power return path from the MOSFET source through the sense resistor will terminate in a short path to bulk capacitor…
