Output Capacitors:
The PT6700 series requires a minimum ouput capacitance of 330µF. The maximum allowable output capacitance is 15,000µF.
Input Filter:
An input filter is optional for most applications. The input inductor must be sized to handle 12.5ADC with a typical value of 1µH. The input capacitance must
be rated for a minimum of 1.6Arms of ripple current. For transient or dynamic load applications, additional capacitance may be required.
