R-REF02-78S Series

  • 3.3V from a single AA battery (boost converter)
  • Efficiency 93%, >80% at 10% load
  • Input voltage range down to 0.65V
  • 0.100" (2.54mm) pin output
  • 3.5mm mounting holes

The R-REF02-78S generates 3.3V from a single AA battery and can directly be used in any application. The reference design contains an AA battery holder and an R-78S3.3-0.1 boost converter. Two jumper headers J1 and J2 ensure connectivity to the output voltage and the CTRL pin of the R-78S converter. The jumper header pins are standard 0.100" (2.54mm) pitch for which there are several mating connectors available. Two 3.5mm mounting holes are provided to allow snap-in or screw mounting. An enable pin puts the R-78S into sleep-mode where it draws only 7uA from the battery.
