dear
The inductance and capacitance are calculated. According to the formula in DS, the inductance value is 4.8 uh and the capacitance value is 0.39 uf, which is quite different from the recommended value (2.2 uh, 10 UF) .
1. Is there an error in the calculation?
2. If there is no problem with the calculation, do you choose by the calculated value or the recommended value? Our application is as follows: input voltage = 3.3 V output voltage = 0.9 v load current-200 ma ripple voltage estimate = 0.9 * 0.01 = 0.009 v
any advice?thanks in advance
