Up0104s Datasheet Patched

The UP0104S is a specialized linear voltage regulator manufactured by uPI Semiconductor Corp (sometimes listed under UIMICRO). It is primarily used in computer hardware, such as motherboards and graphics cards, to provide stable power to low-voltage components. Key Technical Specifications

Select MOSFETs:
Use logic-level or 4.5V-gate drive types. Match Qg for switching losses.

The UP0104S is frequently used in high-density interconnect applications where PCB space is limited. Common use cases include:

Typical applications

Future Research Directions

Protections: Includes built-in thermal shutdown and current limiting to prevent the chip from burning out during a short circuit. 3. Pin Configuration (Pinout)

Final Note

The UP0104S is a robust, simple synchronous buck controller for moderate to high current, but its exact specifications vary by manufacturer and suffix (e.g., UP0104S vs UP0104P). Always refer to the official datasheet for absolute maximum ratings and exact pinout.

Switching Frequency: Operates at a high fixed frequency (often around ) to allow for the use of small inductors and capacitors. Features
