Datasheet for the UP8801S, a 198 KB PDF, identified only by its part number. Datasheets give the pinout, package marking, typical application circuit, electrical limits and recommended operating conditions for the IC. A technician uses one to check expected voltages on each pin, identify the enable and feedback pins, and choose a correct replacement. Compare the marking on the chip with the package codes in the document, as a single part number can cover several variants. Any PDF reader opens the file.
