The UP0104S is frequently used in high-density interconnect applications where PCB space is limited. Common use cases include:
: A key feature is its adjustable output voltage, determined by external resistors. The feedback pin (Vfb) has a reference voltage of 0.8V . The output voltage is calculated using the following formula: VOUT = 0.8V * (R1 + R2) / R2
