Dear Texas Semiconductor,
I have a request for a led driver of 40W supplied with 230Vac.
The leds are made by a string of 18 leds, each one with 3V of voltage forward. The led current is 0.7 - 0.8A. The led configuration is in series.
The circuit doesn't need to be isolated, but it needs a PF minimum of 95% and of a THD better than possible (the machine should be certificated).
Is a TPS92075 a good choice for my application? I though to use the buck configuration...
Using the TPS92075 design calculation it seems possible to achieve such power.... Am I right?
