We recommend to choose modules with a heat sink for enhanced heat dissipation and applications with extreme temperature requirements; ②The minimum input voltage and starting voltage of A2S and A4S Model are 1VDC higher than those of DIP package due to input reverse polarity protection function; ③Exceeding the maximum input voltage may cause permanent damage; ④Efficiency is measured at nominal input voltage and rated output load; efficiencies for A2S and A4S Model’s is decreased by 2% due to the input reverse polarity protection circuit.
