Chosen by audiophiles and sound engineers to power portable audio amplifiers where power noise directly corrupts sound quality. Procurement and Cross-Referencing
: Operates at a high fixed frequency (often around ) to allow for the use of small inductors and capacitors. Features
Desolder Pin 6 (VOUT) or lift the output trace entirely.
The is more than just a collection of pins and voltages; it is a robust, flexible solution for dual-rail power conversion. Whether you are repairing a vintage motherboard, designing an embedded system, or simply expanding your bench knowledge, the datasheet is your definitive guide. Up0104s Datasheet

Beware of fake or incomplete "datasheet" websites that only provide a pinout without electrical tables. To obtain the genuine (revision 1.2 or later), use these sources:
High logic activates the IC; low logic places it into low-current standby.
Feedback input for adjustable versions / Voltage output monitor. The is more than just a collection of
The chip's output voltage is set by a simple resistor divider connected to its feedback pin (Vfb). The community-derived formula is:
