* ISR-will operate down to no load with reduced specifications. Please note that this product is not short-circuit protected.
** The minimum input voltage is 3.1V or V
out
+1.2V, whichever is greater.
Output Capacitors:
The PT7602 series requires a minimum ouput capacitance of 330碌F for proper operation. Do not use Oscon type capacitors. The maximum
allowable output capacitance is 7,500碌F.
Input Filter:
An input filter is optional for most applications. The input inductor must be sized to handle 10ADC with a typical value of 1碌H. The input capacitance must be
rated for a minimum of 1.0Arms of ripple current. For transient or dynamic load applications, additional capacitance may be required.
