Switching regulator til single-celle forsynede IoT-applikationer
RECOM er klar med ny single-celle boost switching regulator med lavt standby forbrug (in english).
Dette er en prøve. RECOM's new Boost R-78S switching regulators have been specially designed for single-cell powered IoT applications. 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 simple 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 160uA, reducing to 7uA 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°C up to +100°C and are certified to the new EN62368-1 standard.
