Notes:
(1) The ISR will operate down to no load with reduced specifications.
(2) Boost topology ISRs are not short circuit protected.
(3) The PT5540 Series requires a 100μF electrolytic or tantalum capacitor at both the input and output for proper operation in all applications.
(4) For operation below 0°C, the output capacitor C
must have stable characteristics. Use either a low ESR tantalum or Oscon capacitor.
(5) See SOA curves or consult factory for the appropriate derating.
(6) The case pins on the through-hole package types (suffixes N & A) must be soldered. For more information see the applicable package outline drawing.
