Hi Team

1.Please provide Example Schematic (Vin = 12V, Vout = - 4V)?

2.(Vin = 12V, Vout = - 4V)This is good design for LMZ22010 ?

3.There are more suitable IC for this condition ? (Vin = 12V, Vout = - 4V , Iout = 8A)

Thank you very much

Hi,

I dont think this part will have enough current capability because the Duty cycle is about 0.25.
Therefore the max Iout that the part can do is (1-D) x 10A = 7.5A. That is approximating with 100% efficiency
See this note for detail
