Dear LA1209,
The UCD is based on SODA topology, Self oscillation digital amp. i.e not running at FF mode. (Fix frequency mode)
For the SMPS, there are some topology in the market,
Flyback switching SMPS
Full bridge SMPS
Half bridge SMPS
Resonant SMPS
For this 4 kinds, it is running on :
QR, FF and both. (Small power Burst mode, mid power FF, High power QR, like Infineon TDA16888 and Philips TEA1533 series.
If using for Audio amp, Resonant SMPS is preferred.
But there are very few resonant SMPS controller in market.
Hope this help.
