Hello team,
Customer wants to know how to design the external components parameters, work conditions: 48V battery, Vout = 12V, Iout = 1.5A.
1. Non-sync Buck, for the output diode, how to choose the rated current parameter? For RC filtering of diodes connected in parallel, how to choose the resistance value, capacitance, withstand voltage, and power of R and C?
2. The inductance value is calculated to be 68uH according to 30% ripple current, is there a problem with the actual use of 100uH?
The actual output is 1.5A, how to choose the rated current of the inductor? Do I have to follow the manual recommendation of at least 4.5A?
