hi ArTzy
I double checked TPS92561 and found that this is actually a boost controller. while after rectifier, the peak voltage is like 230V*1.414, which is for sure high than output LED string voltage (even series all 70LEDs) . I think TPS92410 would be…
Other Parts Discussed in Thread: TPS92410 Hello,
I am trying to design a Extra Low Voltage traffic lantern that meets the following specifications:
VIN = 24-50VAC
IOUT = 350mA
Power Factor >= 0.9 lagging and >= 0.99 leading
THD <= 5%
Dimmable…
Part Number: TPS92410 Other Parts Discussed in Thread: TPS92411 Hello guys,
One of my customer is considering using TPS92410 for their next products.
They want to drive 20~25pcs of white LED from AC100V with 20~30 mA, small parts count and no isolation…
Part Number: TPS92410 Other Parts Discussed in Thread: TPS92411 Hi,
Can TPS92410 operate without the TPS92411?
I allow not to control current value of each LEDs.
Best Regards,

Part Number: TPS92410 Other Parts Discussed in Thread: TPS92411 Hello Team,
For TPS92410 and TPS92411,
Can this solution be used for universal input supply range?
Can this support design up to 30W?
What is max conversion efficiency achieved with this…
Part Number: TPS92410 Hi There!
I'm using the TPS92410 for a design working at 120VAC and I've found a problem in the over voltage protection section. It recommends to use Rground as 121K and then calculate the Rdrain using the equation. 121E3 * ((120…

I am attempting…
Part Number: TPS92410 Hi Support,
Customer is driving the Osram Duris E3 LED for Highbay. There will be 4 string parallel and 10++ LED in Series and they need a PWM Dimming function.
In addition, they need boost topology (non-isolated), universal input…
Part Number: TPS92410 Is the 1.5V of the ADM(limit) derived from or proportional to the 3V reference voltage?
Both are specified as +/- 5% tolerance
If derived then: If the 3V reference is at 3V +5%, then the 1.5V ADIM(limit) will be at 1.5V +5%
If separate…
