Hello.
To use STEVAL-DPSLLCK1, I am reading user manual(UM2348).
Table 1 says that the resonant frequency is 175kHz,
but Table 8 says that C39,C110 and C130 are 18nF,
and the leakage inductance of T3 (Lr) is 20.32uH.
From table 8 values Cr=54nF and Lr=20.32uH,
If I calculate, the resonant frequency is 152kHz.
Please teach me the reason of the difference of the values,
175kHz and 152kHz.
