Hi Flavio.
1. I do not recommend connecting directly VIN voltage to VDD pin. VDD max voltage it can handle is 30V (see below), which is the same minimum voltage in your case. Rstart should be designed at the lowest line voltage (30V) conditions and to…
Hey Hong Huang,
I hope you're doing well. I've been encountering a few issues with our design that I could really use your expertise on. Here's a breakdown of what's been happening:
Primary Side Issue: Mosfet Premature Clamping
I've…
Part Number: UCC28C50 Hi,
I want to design a system with
input: 55VDC-150VDC output 48 VDC @ 2.5 Amp peak\
1. In UCC28C56EVM can we use the same design and replace it with web bench design calculations?
2. We need small PCB footprint for this so is…
Part Number: UCC28C50-Q1 Other Parts Discussed in Thread: UCC28C50 Hi
we are building a ± 12V @ 4A output where input is 230VAC 50Hz is it possible to build the dual supply using single IC? if there is a reference design please let me know.
Part Number: UCC28C56EVM-066 Other Parts Discussed in Thread: UCC28C50 Hi Team,
My customer wants to test UCC28C50 on the UCC25C56EVM. How do I modify the EVM to make sure the work is normal? thanks.
Part Number: UCC28C50-Q1 Other Parts Discussed in Thread: LM5180 , LM25183 Hi Team,
I'm looking for designing an isolated bi-polar power supply with fly-back topology for my Mosfet Gate driver circuit. I'm little confused on selecting right controller…

Hey TI Team, I hope you are doing well. I needed your recommendation on using UCC28730-Q1 for DC-DC applications such that it meets the below…
Part Number: WEBENCH-POWER-DESIGNER Other Parts Discussed in Thread: UCC28C40 , UCC28C50 Hi, I'm designing a flyback topology with the UCC28C50Q controller. I need to run the simulation using a Wurth coil that is not includef to the alternative parts…
I have not implemented a PWM flyback controller in this design yet. I have been trying to drive it directly from my microcontroller. If I need a PWM flyback controller I have been looking at UCC28C50-Q1.
Hi,
Q1, UCC2891 VIN needs minimum 18V to start, if not using VIN, but VDD, it is minimum 13.2V. So for 9V input, you need to add external circuit to make UCC2891 to start
Q2, UCC2800, or UCC28C50
Q3, yes, or use TINA TI.
