Hi guys:
I am just getting involved in a DC-DC project,since the input voltage is high than 15V and our process is about 5v cmos process,so I need to design a inner regulator as a supply for the circuit.
But for the regulator,I don't know how to decide its specification,such as ,bandwidth,the value of output cap,startup time?
Has someone ever met the same difficulty as me?
