XC9235/XC9236/XC9237 Series ETR05014-017a 600mA Driver Tr. Built-In, Synchronous Step-Down DC/DC Converters ■GENERAL DESCRIPTION ☆Green Operation Compatible The XC9235/XC9236/XC9237 series is a group of synchronous-rectification type DC/DC ☆coGnvreeertneOrspweritahtiaonbuCilot-minp0a.4tib2Ωle Pchannel MOS driver transistor and 0.52Ω 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:±2.0%), the output voltage can be set from 0.9V by using two external resistors. The A/B/C/E/G types have a fixed output voltage from 0.8V to 4.0V in increments of 0.05V (accuracy:±2.0%).
