Part Number: UCC28C56H-Q1 Tool/software: Good morning Team,
I am working on power supply design for Inverter. So, decided to go with Flyback for HV DC-DC converter. Could you suggest me PWM controller IC's for the below specifications.
Specifications…
Part Number: UCC28C56H-Q1 Tool/software: Hello All,
I am using the UCC28C56H-Q1 controller in a flyback design to take 120V nominal and output 5V at up to 25W. If the output load is 10 ohm, the output voltage is 5V and power is ~2.5W. When the output…
Part Number: UCC28C56H-Q1 Tool/software: Dears:
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 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.
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…

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: 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 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 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 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…
