First of all, I apologize that the part number in the post is not appropriate.
As far as I know, most LED driver products are unable to output low currents…
Part Number: TPS61169 Hi Sir,
My customer asked some questions about the TPS61169, does it support the PWM dimming frequency at 250Hz?
If it can support the 250hz dimming, what is the range of PWM dimming signal duty cycle?
Follow the datasheet mention…
Part Number: TPS61169 We are trying to drive some higher current UV LEDs. Based on the data sheet, with a sense resistor of 0.58 ohms we should be getting 352mA
However when measured it is more like 150 mA max.
It appears that there is too much noise…
Part Number: TPS61169 The TPS61169 datasheet includes recommended inductors, which makes me think that there might be reasons for similar inductors to not be suitable? Specifically, the recommended inductors are not easily available to me so I'm wondering…
