Part Number: UCC2894 Other Parts Discussed in Thread: PMP7391
Hello Team,
I/m working with UCC2894 PWM controller and I have referred "PMP7391" reference design of TI for active clamping circuit. The blue waveform is @TP15, yellow waveform is @ primary…
Part Number: UCC2894 Other Parts Discussed in Thread: PMP7391 , , UCC2897A Hello,
Looking for Active clamp Forward (High Side) design for 300VDC to 400 VDC input with 24V / 300W output. Came across PMP7391 reference design.
Need any excel or MathCad based…
Hi Umamaheswararao,
If you use the UCC2897A, UCC2891, or UCC2893, then these devices have a built in JFET from the VIN pin to VDD that allows the input voltage to charge the VDD bias supply capacitors directly. This eliminates the need to the additional components…
Hi,
It looks you are asking same question and based on the same circuit. Please look at the below link. I assume you are doing the same design by comparing the circuit. If this is true, then please use one thread and the below which it looks the debugging…
Part Number: UCC2894 Other Parts Discussed in Thread: UCC2891 , UCC28C42-Q1 , UCC28C52-Q1 Hello, I am trying to design an active clamp flyback with UCC2894D for an automotive application. The temperature requirement is 105 degC. According to the data given…
Part Number: UCC2894 Hi Team,
I have started testing the UCC2894D for my application. the following circuit is connected to verify the operation
Testing steps
1. Vref voltage is coming 5.21V when VDD supply is increased from 12V to 12.7V (initially) …
Part Number: UCC2894 Hi team,

Part Number: UCC2894
Hello,
I am trying to get ucc2894 working,
but output always no signal,
the IC get VDD is 13.5V, Vref 5V, LineOV less than 1.27, LineUV greater than 1.27V,
the dirve signal (FB) give 4V, CS connect to GND,
is there other condition…
