Part 7: Testing and Verification After Schematic Completion

Once the schematic is drawn and the PCB is fabricated, perform these tests to validate your work: Websites like Digikey , Mouser , or ChipMLCC

  1. No-load output voltage – Should be within ±2% of target.
  2. Load regulation – Apply 0% to 100% load, measure voltage drop (<3%).
  3. Switching node waveform – Use an oscilloscope on SW pin. Look for clean square waves with <5% overshoot.
  4. Thermal image – At full load, the IC should not exceed 85°C.
  5. Power Good timing – Ensure PG asserts after Vout reaches 90% of nominal.

If any test fails, revisit the compensation network or PCB layout (feedback loop area, ground vias).
