| Issue | Likely Cause | Solution | |-------|--------------|----------| | No output voltage | Enable pin not pulled high or input voltage below UVLO | Connect EN to VIN or apply >1.2V; ensure input supply is >4.5V | | Output voltage ripples >50mV | Inadequate output capacitance or poor layout | Add a 10µF low-ESR ceramic capacitor at the load; re-route SW node | | Overheating under light load | Wrong inductor choice (saturation) | Use an inductor with higher saturation current (>4A) | | Audible noise from inductor | Auto-PFM mode at light loads causing sub-audible frequencies | Force PWM mode by pulling MODE pin high |
