Part Number: UCC28C53 Other Parts Discussed in Thread: UCC28C55 , , UCC2800 , UCC28C54 Hi
I have design SMPS using UCC28C55 . I am start designing one solution on below both requirement. I have done schematic and also attached please review and comment…
Part Number: UCC2891 Other Parts Discussed in Thread: UCC28C50 , UCC2800 , LM5025A , LM5026 Hello guys,
One of my customers is considering using UCC2891 for their new products. They want to design a isolated power supply which has Vin=9~36V(DC), Vo…
Hello,
You should be able to use the UCC2800 in a buck converter. The device has internal soft start.
The following application brief explains how this works.
You also may need to use a gate drive transformer to drive the high side FET.…
Hi Prabhakara,
The datasheet for the controllers have a step by step design guide that takes you through the design calculations.
See section 10 of the UCC2800 datasheet as an example.

Hi Sheldon,
TI has many cost effective PWM controllers that can output 50% duty cycle, UCC28C4x family, UCC281x, UCC2800 .
Can you clarify what you mean by part to part slew rate?

Part Number: UCC2801 Other Parts Discussed in Thread: UCC2800 , UCC2802 , UCC2804 UCC2801
Ct=220pF
Rt=36.5k
I am expecting an output frequency between 75kHz and 87 kHz, but I am getting 91.88 kHz. Confirmed in time domain and via FFT.
However…
Part Number: TPS40210 Other Parts Discussed in Thread: UCC2800 I am looking for an upgraded PWM to the UCC2800 with an integrated soft-start and enable circuit and was able to find the TPS40210. The current UCC2800 is used in a fixed off time circuit…
Part Number: UCC2803 Other Parts Discussed in Thread: , LM431 , UCC2813-0 , UCC2800 Hi Team,
Could you help our customer and clarify the usage of UCC2803 controller IC.
Here is their concern:
"There is an input resistance mentioned as RH which is…
Hi Someno-san,
I cannot find a single channel PWM with a sync pin.
The oscillator on the UCC28C4x and UCC2800 family of devices can be sync'ed to an external source and both sets of device have variants that have duty cycles that can extend to 90…
