Eval board demos switching regulator for battery-driven IoT designs

RECOM’s first evaluation board allows engineers to test the functionality of the R-78S switching regulator, which boosts a AA battery or external supply voltage to 3.3V for low power IoT applications. The evaluation board is equipped with several jumper headers measuring input and output current and voltage – allowing typical battery lifetime calculations in both active and standby mode.

The R-78S Evaluation Board demonstrates the performance of the R-78S which boosts single-cell AA battery voltage of 1.5V up to a stable 3.3V. This guarantees much higher energy capacities and reduces maintenance costs compared to button or coin cell batteries. This will effectively extend the operation lifetime of an application since the boost converter continues to operate at input voltages as low as 0.65V.
