Specially designed for single-cell powered IoT application, RECOM announce boost R-78S switching regulators. Due to their wide input voltage range, high efficiency and low stand-by losses, they extend not only the working lifetime of the cell, but also maintain a stable 3.3V output down to 'the last gasp' battery voltage.
Based on the plug-and-play concept of the standard R-78 buck regulator, the R-78S boost regulator is able to provide a stable 3.3VDC output from a lower input voltage from 3.15V down to 0.65V.
Applications such as microcontrollers, WLAN/Bluetooth/LoRa modules or IoT systems can now be supplied from a single 1.5V cell, which, in contrast to conventional 3V button batteries, offers considerably more power for a longer operational life.
The efficiency of the R-78S series can reach 93% at full load, and can maintain at over 90% even under light loading. No load current consumption is 160μA, reducing to 7μA when the control pin is used.
The converters are protected against permanent short circuit and over-temperature conditions and have an under voltage lockout to protect rechargeable cells from deep discharge. They can be operated in ambient temperature range from -40 up to 100°C and are certified to the EN62368-1 standard.
The R-78S comes with a three year warranty. Samples are now available from all authorised distributors.
