I will use LTM4613 in my design. Input voltage is about 28V, output is 12V. The system need about 3A from 12V.
Because of mechanical contraints I can't use 100uF input bulk capacitor. Instead of bulk capacitor, can i use multiple 10uF ceramic or tantalium capacitors?
Bulk electrolytic input capacitor is not required, this capacitor is in place on the demo board in case significantly inductive input cables were used on the input (input ringing). In either…
Yes. Ceramic caps and tantalum caps can be used.
