Features Evaluation Module • 3.3V from a single AA battery or from an external source (boost converter) • Efficiency 93%, >80% at 10% load • Input voltage range down to 0.65V • Input and output power measurement capability Evaluation Module • Micro-USB type B or 0.100” (2.54mm) pin output Description The R-78S3.3-0.1-EVM-1 Evaluation Module generates 3.3V from a single AA battery or from an external source. By using the external input source, any voltage source (other types of batteries, energy harvesters, etc.) in the range from 0.65V to 3.15V can be used. The evaluation module contains a AA battery holder, power switch, R-78S3.3-0.1 boost converter and a micro-USB connector. Jumper headers are provided to allow various test measurements to be made. An enable pin puts the R-78S into sleep mode where it draws only 7uA from the battery. Selection Guide Part Input Output Output Efficiency (1) Max.

Note: to reduce the power consumption, no indicator LED is fitted. Remember to switch off to conserve the battery. • The output voltage is accessed via J7 or the USB port. • To measure the input and output...
