The XC9235/XC9236/XC9237 series is a group of synchronous-rectification type DC/DC converters with a built-in 0.42? P-channel MOS driver transistor and 0.52?N-channel MOS switching transistor, designed to allow the use of ceramic capacitors. Operating voltage range is from 2.0V to 6.0V (A?C types), 1.8V to 6.0V (D?G types). For the D/F types which have a reference voltage of 0.8V (accuracy:
