ISR-will operate down to no load with reduced specifications.
The minimum input voltage is 3.1V or Vout+1.1V, whichever is greater.
For operation below 0擄C, Cin and Cout must have stable characteristics. Use either low ESR tantalum or Oscon廬 capacitors.
See Safe Operating Area curves.
If the remote sense ground is not used, pin 7 must be connected to pin 8 for optimal output voltage accuracy.
Output Capacitors:
The PT6702 requires a minimum ouput capacitance of 330碌F for proper operation. The maximum allowable output capacitance is 15,000碌F.
Input Filter:
An input filter is optional for most applications. The input inductor must be sized to handle 10.0ADC with a typical value of 1碌H. 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.
