Notes:

(1) The ISR will operate at no load with reduced specifications.

(2) The stated maximum input voltage assumes the nominal output voltage. If the output voltage is adjusted (trimmed) to some other value, consult the

related application note on output voltage adjustment for the revised input voltage limitations.

(3) The STBY* control (pin 4) has an internal pull-up and if it is left open circuit the module will operate when input power is applied. The open-circuit

voltage is low (less than 5V). Consult the related application note for interface considerations.

(4) For guidance on suitable input and output capacitors consult the accompanying application note, “Capacitor Recommendations for the PT6880 Series.”

(5) See Safe Operating Area curves or contact the factory for the appropriate derating.

(6) During solder reflow of SMD package version do not elevate the module case, pins, or internal component temperatures 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).

(7) The case pins on through-hole package types (suffixes N & A) must be soldered. For more information consult the applicable package outline drawing.
