Part Number: UCC2804 Tool/software: Hello,
I want to use the UCC2804 to control flyback converter.
The example in the datasheet is about CCM flyback with current peak mode.
I'm looking for an example of DCM flyback with current peak mode. I can read…
Part Number: UCC2804 I am doing a qualification on part UCC2804QDREP and I wanted to know all conditions necessary to get the measurement that TI got for the open loop voltage gain test. The minimum value is 60 dB according to the data sheet. How is that…

Part Number: UCC2804 Other Parts Discussed in Thread: UCC1804 , Hi,
In datasheet, it says that the
operating free air temperature is up to 125C
operating junction temperature is also 125C.
Why these 2 temp could be the same since junction temp should always…
Part Number: UCC2804 Hi Team,
There seems to be a discrepancy between the electrical specs max operating temp of the UCC2804D (125C) and the package addendum (85C). A similar E2E post stated that "This part may be operated up to a max junction temperature…
Part Number: UCC2804 Hello, I'am using the Ucc2804 pwm controller for a dcm flyback converter ( Fsw = 300kHz). The overcurrent protection ( Hiccup mode) does not work during an output shortcircuit. The PWM works in cycle-by-cycle current limiting mode…
Hello Bolin,
Yes, UCC28180 or UCC28019A are suitable PFC options. The UCC28019A is hard-wired for 65kHz and provide a Brown-out function. The UCC28180 can be programmed for 67kHz, but has no BO function.
In any case, the DC/DC converter will need to be…
