Filter/Capacitor Selection

Output Capacitors: The PT6705 requires a minimum ouput capacitance of 330µF for proper operation. 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 10ADC with a typical value of 1µH. The input capacitance must

be rated for a minimum of 2.0Arms of ripple current. For transient or dynamic load applications, additional capacitance may be required.

(Note B)

Note A:

All data in the above graphs has been developed from actual products tested at 25°C. This data is considered typcial for the ISR.

Note B:

SOA curves represent the conditions at which internal components are at or below the manufacturer’s maximum operating temperatures.
