Driver for WS2812, SK6812 or similar LED strips controlled via Bluetooth LE. It supports RGB and WWA LEDs. The drive uses motion and light sensors so in automatic mode it can turn on the lights when it detects the presence of someone in the dark.
This document introduces a highly compact and cost-effective step-down power supply designed using the LYTSwitch-0 series device (LYT0006D).
The power supply can operate from an input voltage range of 90 to 132 VAC. The DC bus voltage is high enough to support a 38 V output when using a buck topology. In a buck converter, the output voltage must always be lower than the input voltage. In addition, the output voltage is also limited by the maximum duty cycle of LYTSwitch-0, which also requires that the input voltage must be higher than the output voltage.
