Notes: (1) The ISR will operate down to no load with reduced specifications.
(2) Specified as “Open-Circuit.” Either an “open-collector” bipolar transistor, or “open-drain” MOSFET is recommended for controlling this input.
(3) See Safe Operating Area curves or contact the factory to determine the appropriate derating.
Input Filter: To facilitate the high output fast trqansient performance, a high quality 2,000F input capacitor(s) is required for the PT8000 series. Use either
tantalum or Oscon type capacitors with a maximum ESR (equivalent series resistance) of 20m
