Part Number: TPS92074 Hello:
Too bad , earlier posts did not go through.
In TPS92074 CHIP, calculations can be done to get buck-boost mode.
But how do you set output voltage?
Is the meaning here "buck-boost" so that the output voltage can be either lower…
Part Number: TPS92074 Other Parts Discussed in Thread: LM3445 , LM3414 Hello guys,
One of my customers is looking for a LED driver device which has the following features.
1. It is the device which has the buck topology with a external NMOSFET like TPS92074…
Part Number: TPS92074 Hi Tiers: i need develop a LED driver,The topology is the APFC+BUCK,
input: AC120-240V, output: 50-240V/ 1A, need support PWM and Analog dimming.
does the TPS92074 can support this project?
if not, which P/N can support this case…
Part Number: TPS92074 Dear Teams
we have a 100W LED driver project, plan to use PFC+BUCK. The design requirment is ablow, Can we use TPS92074 ? Does it support 135V output ? we find the max output of TPS92074 is 120V from TI web, .
Vin: 176~264VAC
…
Part Number: TPS92074 Dear TI,
Referring to the data sheet of the TPS92074 (SLUSBO7-Aug 2013) I have a question regarding the schematic in Figure 19. I would like to dim the light of the LED-string from 0% gradually up to 100%. But looking at the schematic…
Part Number: TPS92074 Dear TI-forum,
I would like to feed additional circuits (like a micro controller generating a 0-3V dim signal). If so, what is the maximum current I can draw?
Thanks,
Frits

Hi LED Driver team, My customer ia thinking to use TPS92072 under DC Power Input(=95VDC+/-10%) for LED driver. Cond.; VIN = 95VDC, VLED = 72V, ILED = 0.18A, Under this condition, the TPS92074 driving LED is feasible? I wonder if Digital…
Part Number: TPS92074 Hello guys,
One of my customers is considering using TPS92074 for their new products because the device external parts count is low. But their products is needed to keep LED current to avoid LED flickering when AC input voltage goes…
Part Number: UCC28782 Other Parts Discussed in Thread: TL103W , , TPS92074 , TPS65987 , TPS55288 Hello:
In a separate application, we need to have our UCC28782-based module behave as a "current-controlled" source. Such that its output voltage will change…
