Other Parts Discussed in Thread: TPS548A29,
Hi Team,
I have some question as show below when use TPS548A29 EVM to verify, please help check, thanks.
1. How to improve transient response？Could you provide cff calculate formula？
photo 1 is 2.5V/0A~7.5A and photo 2 is 2.5V/7.5~15A
2. Why EVM fsw measurement not match EVM fsw setting？
Use jumper to setting 600kHz(real measurement is 800kHz), 800kHz(real measurement is 1000kHz) and 1000kHz(real measurement is 1300kHz).
photo 3 is 2.5V/0A/FCCM/600kHz(real 840.336kHz) and photo 4 is 2.5V/15A/FCCM/600kHz(real 854.701kHz)
3. Why EVM fsw wavform match EVM fsw setting？
Please refer to photo 5.
Best Regard！
Tom Lin
