Hello
So I'm trying to complete a prelab with the LM3578 switching regulator and I'm having a problem calculating C2. I'm following the example for the Buck Converter circuit and the formula for C2 is:
C2 ≥ Vo (Vin - V0) / (8 * Fosc2 * Vin * Vripple * L1
The given values in there example are:
Vin = 15
Vo = 5
Vripple = 0.01
L = 470u
Fosc = 50 KHz
C2 answer is 200uF rounded off i'm assuming
My calculation is 5 (15 - 5) / (8 * 50KHz2 * 15 * 0.01 *470uH) = C2 35.4uF
Where did I go wrong?
Thanks
