Find the value of Rsc, L and Co for a A7840 switching regulator to provide +5 v at 3A, using the following specifications: toff= 24 s, ripple voltage = 400mA and ton=26 s.

Rsc = 550 m , L = 25 H & Co = 75 F

Rsc = 55 m , L = 25 H & Co = 750 F

Rsc = 550 m , L = 25 H & Co = 75 F

Rsc = 650 m , L = 25 H & Co = 65 F

Rsc = 720 m , L = 25 H & Co = 250 F
