i am facing the TPS 92560 can’t produce enough current ( 0.1A ) at the gate pin to the NXP PMT200EN mosfet (gate pin which required demand current ( 0.5A ) from the TI LED driver themselves. This will cause the voltage drop look like a big sine wave…
Hello,
The Power Integrations part is a non-isolated part. It also has an internal MOSFET. The non-isolated parts we have will need an external MOSFET but that doesn't mean it's a less cost effective solution. It also keeps the heat dissipation of…
Please kindly advise if the TPS92560 has the dimmable function or not? we are targeting to load 36V COB, and enable dimmable function. （ELV，Triac dimmable）, if TPS92560 not workable, do you have any other Model proposed?
Dear Irwin Nederbragt
Thank you for reply.
I replaced the old mosfet as part: CSD17308Q3 ( 5.1nC) but the total power ( Pe_trans + Pdriver + Pled)still is 13W, Pled = 5.4W
=>The power consumption on the driver circuit is 13W-5.4W - 1.5W , about…

I have 2 LED Driver designs built and am using: PMP5112 Rev E and TPS92560 _120V_Boost_A. They both work but want to know how to adjust the current to dim the LED strings.
Part Number: TPS92561 Other Parts Discussed in Thread: TPS92560 I have two kind of battery supply: 2 series Li-Ion battery for 48V 200mA LED and 2 series 12V Lead-Acid battery for 36V 600mA LED (customer request)
I need constant current output, but when…
Hello Loon,
For the case of 24VAC and 32VAC for much of the input waveform you are above the LED stack voltage so the switcher is no longer running and the only current draw is through the linears. The input current waveform will be flat. I expect that…
Other Parts Discussed in Thread: TPS92560 , LM5022 , LM5021 Hello,
We have a controller with a 24VAC supply and need to output 24VDC or 48VDC @ 20W to drive a contactor (it has to be a DC contactor). Unfortunately we have some space limitations and a Ta…
Other Parts Discussed in Thread: TPS92075 , TPS92560 TPS92075 as a simple Boost converter. Looks like all I have to do is not connect the PFC connections, and the chip will work as a Boost converter. Is this correct?
Hi Ben,
Not yet. Should be up to it in the next day or two. But, your idea gave me a thought for a new design change. I'm thinking I should go back to R22 as a fixed 100K resistor. What would you think if I installed a 50K variable resistor in series…
