Hi Power Team!
My customer has an LMZ14203H circuit and needs to know the worst case stability over the following conditions:
1. Vout : 12V
2. Load: Nominal 0.2A, Max: 0.75A (if going in pulse skipping, what freq and ripple voltage)
3. Vin: 24V
4. Worst case phase margin (temp (-40deg to 85 deg, aging – BOL, EOL)
5. Worst case Gain margin (temp (-40deg to 85 deg, aging – BOL, EOL)
6. Input filter: Pi filter : 22uF – 10uH -22 uF (X7R caps)
7. Output filter: 3*10uF IIel 22uF (All ceramics)
Can you help with this analysis? I don't know how to configure the WEBENCH Power Designer Tools to provide the needed stability analysis with these components.
Best regards,
Jim B
