Notes:
(1) This is a typical value. For the adjustment limits of a specific model consult the related application note on output voltage adjustment.
(2) The output voltage of the PT6472 (2.5 V) should not be adjusted higher than 2.5 V.
(3) The Inhibit control (pin 1) has an internal pull-up, and if left open-circuit the module will operate when input power is applied. A small low-leakage
(<100 nA) MOSFET is recommended to control this input. See application notes for more information.
(4) A 470 μF electrolytic input capacitor is required for proper operation. The capacitor must be rated for a minimumm of 0.7 Arms of ripple current.
(5) An external output capacitor is not required for basic operation. Adding 330 μF of distributed capacitance at the load will improve the transient response.
(6) For operation below 0 °C, C
must have stable characteristics. Use either low-ESR tantalum or Oscon type capacitors.
(7) See SOA curves or consult factory for the appropriate derating.
(8) During solder reflow of SMD package version do not elevate the module case, pins, or internal component temperature above a peak of 215 °C. For
further guidance refer to the application note, “Reflow Soldering Requirements for Plug-in Power Surface Mount Products,” (SLTA051).
(9) The case pins on the through-hole package types (suffixes N & A) must be soldered. For more information see the applicable package outline drawing.
