    For more information on the UP0104S datasheet, we recommend consulting the following resources:


    | Symptom | Likely Cause | Datasheet Checkpoint | | :--- | :--- | :--- | | No output, VCC present | IC in UVLO or disabled | Measure EN1/EN2 (Pins 13 & 5). Must be >2.0V. Check VCC >4.3V (Pin 4). | | Output voltage too low | Feedback divider wrong or output short | Verify FB pin voltage (Pins 1 or 14). Should be exactly 0.8V. If lower, output is shorted or divider is incorrect. | | MOSFETs burning hot | Cross-conduction or wrong frequency | Check UGATE and LGATE dead-time (requires oscilloscope). Replace with matched MOSFETs from datasheet spec. | | Intermittent startup | SS capacitor leakage or unstable COMP | Inspect the soft-start capacitor (Pin 3 for Ch2, shared for Ch1). Leakage here prevents ramp-up. |
