r-78s prolongs
RECOM's R-78S switching regulator has been specifically designed for single-cell powered IoT applications. Due to its wide input voltage range, high efficiency and low stand-by losses, it extends the working lifetime of the cell. Based on the simple plug-and-play concept of the standard R-78 buck regulator, the R-78S boost regulator is able to provide a stable 3.3 VDC output from a lower input voltage from 3.15 V to as low as 0.65 V. Applications such as microcontrollers, WLAN / Bluetooth / LoRaWAN modules or IoT systems can now be supplied from a single 1.5 V cell. In contrast to conventional 3 V button batteries, this offers considerably more power for a longer operational life. The efficiency of the R-78S series can reach 93% at full load and 90% under low load. It offers a low standby power consumption of only 7 μA when switched off with the integrated control pin. It can be operated in ambient temperature range from -40°C to +100°C and is certified to the new EN62368-1 standard.
