Hello TI Team,
I am working with TI excel sheet to design 3V3@ 25A output by using TPS546C23
S546C23 Excel Calculator and Layout Checklist
https://www.ti.com/lit/zip/slurb05
The Buck inputs are
| Parameter | Specification | Units |
| Minimum input voltage | 11.4 | V |
| Maximum input voltage | 12.6 | V |
| Switching frequency | 3.00E+05 | Hz |
| Output voltage | 1 | V |
| Maximum output continuous current | 15 | A |
| Maximum operating ambient temperature | 85 | deg C |
| Peak-to-peak Input Voltage Ripple | 1.00E-01 | Vpp |
| Expected Efficiency | 0.85 | - |
| Peak-to-Peak Output Voltage Ripple | 5.00E-03 | Vpp |
| Peak-to-Peak Output Voltage Overshoot | 1.00E-02 | Vpp |
| Load transient Starting current level | 1.5 | A |
| Load transient Final current level | 9 | A |
while putting the inputs in TPS546C23 Excel Calculator and Layout Checklist, I am getting design waring of LC resonance frequency.
Can someone helps to clarify and resolve this problem?
Your quick response in this regard will be highly appreciable?
Regards
Kapil
