Camera flash based on the STCF07
  • active Active

The STEVAL-TLL009V1 demonstration board demonstrates the performance of the STCF07, a dedicated and size-optimized solution for driving a power LED.

This device is a buck-boost converter which guarantees proper LED current control over all possible battery voltage and LED forward voltage conditions.

The output current control ensures good current regulation over the forward voltage spread characteristics of high-brightness LEDs.

The device also includes various functions to protect the chip and the power LEDs, such as an optional external NTC that is supported to protect the LEDs against overheating.

It is possible to separately program the current intensity in HIGH and LOW mode using the SEL pin.
