Non-condensing
(1) ISR will operate down to no load with reduced specifications Please note that this product is not short-circuit protected.
(2) The PT7700 series can be easily paralleled with one or more of the PT7749 slave modules to provide increased output current in increments of 15A.
Please contact Power Trends for the appropriate application note.
(3) The minimum input voltage is 4.5V or V
out
+1.2V, whichever is greater.
Output Capacitors:
The PT7700 series requires A minimum output capacitance of 1200碌F for proper operation. To reduce ESR, Power Trends recommends using four 330碌F
electrolytic capacitors in parallel.
Input Filter:
An input filter is required for all applications. The input inductor must be sized to handle 15ADC with a typical value of 1碌H. The input capacitance must be rated
for 14Arms of ripple current. Power Trends recommends using four Sanyo OSCON style capacitors with a 3.5Arms ripple current rating in parallel (p/n 6SA330M).
