Up0104s Datasheet [verified] -

Here’s a useful, structured write-up for understanding and using the (a common PWM step-down DC-DC controller IC, often used in motherboard VRM or other power regulation circuits).

For production line purchasing or bench repairs, authorized sourcing channels keep updated stocks available:

The is a high-performance 3A Low Dropout (LDO) linear regulator typically manufactured by uPI Semiconductor Corp (often listed via distributors like Veswin Electronics or Jotrin Electronics ). It is designed for applications where high current delivery, low noise, and space efficiency are critical, such as in personal electronics and data center computing. Key Technical Specifications Up0104s Datasheet

Desolder Pin 6 (VOUT) or lift the output trace entirely.

: Voltage regulation, sub-system power management, and high-speed signal conditioning. Here’s a useful, structured write-up for understanding and

Usually features a dropout as low as 400mV at full load.

If the uP0104S chip becomes burning hot immediately after connecting the power supply, it indicates one of two primary issues: Key Technical Specifications Desolder Pin 6 (VOUT) or

Vout = Vref × (1 + Rtop/Rbottom) , where Vref = 0.8V (typical). Example: For 1.8V, choose Rbottom = 10kΩ, Rtop = 12.5kΩ.
