I have a PW.168W2.801 PSU that is getting no power on the 5v SB pin, nothing looks burnt on the PSU itself, I have removed everything and Im getting over 300v on the main capacitor. I have the LED cable connected in the pic but have removed it for testing, any help is appreciated. -
I'm designing an ESP-based WLED controller board for WS2815 12V LED strips, with a primary focus on energy efficiency.
To minimize power consumption, my goal is to completely shut down the system when the LED strip is turned off.
However, the current buck converter powering the ESP module draws about 8 watts even when the LEDs are idle, making it unsuitable for low-power operation.
I am using below components:- Buck Converter: TPS562201 (12V → 5V regulated)
- Microcontroller: XIAO ESP32-C3 (with built-in USB-C)
- LED Strip: WS2815 (12V digital LED strip)
- Switching
