Part Number: TPS92643-Q1

Hi Team

Do we have products to meet the following specs? THX

1.Applied to vehicle blind spot detection alarm LED (placed on A-pillar) measurement control
2. Fixed output current (regardless of LED Vf)
3. The output current can be dynamically adjusted (eg 40mA during the day, 10mA at night)

Hello Kygo,

What is the input voltage range, the LED voltage range and the number of LEDs? The TPS92643 can operate at these low currents as a constant current source, but I think it is a expensive solution when compared to linear LED drivers.

I would start here:

You will have to filter on the number of channels, Vin range, sink or source, etc...
