Notes: (1) The sum-total current from Vo1 & Vo2 must not exceed 20ADC.
(2) This is a fixed parameter. Adjusting Vo1 or Vo2 higher will increase the module’s sensitivity to over-voltage detection. For more information, see the
application note on output voltage adjustment.
(3) The EN1 and EN2 control inputs (pins 3 & 4) have internal pull-ups and may be controlled with an open-collector (or open-drain) transistor. Both
inputs are diode protected and can be connected to +Vin. The maximum open-circuit voltage is 5.4V.
(4) Voltage output at “TEMP” pin is defined by the equation:- VTEMP = 0.5 + 0.01T, where T is in °C. See pin descriptions for more information.
(5) See SOA curves or consult the factory for the appropriate derating.
(6) The case pins on the through-holed package types (suffixes N & A) must be soldered. For more information see the applicable package outline drawing.
