A small buck converter that delivers a constant current, ideal for driving one or more high-power LEDs in series. By default the module delivers a constant current of ~278mA, but when the solder bridge is connected, it delivers ~556mA. In addition, the brightness of the LED(s) can be controlled using a PWM signal (2.5-5V) or an analog signal (0-2.5V) on the CTRL pin. In the default setting, this driver is also very well suited for controlling our flexible LED strings.
