Datasheet
## • Boost converter Features • Efficiency 93% , >80% with 10% load • Input range down to 0.65V **DC/DC Converter** • Continuous short circuit protection Switching • 7µA input current in standby Regulator • -40°C to +100°C operation **R-78S** • IEC/EN62368-1 certified, CB report ee ~~—~~ Description **0.1 Amp** The R-78S is a DC/DC boost converter designed to run from single cell batteries. The **SIP4** arras fi input voltage range of 0.65V-3.3V means that alkaline, NiCd, NiMH, zinc-carbon or lithium chemistry cells can be used to generate a stable 1.8V, 3.3V or 3.6V output to power microprocessors, WLAN/Bluetooth modules and IoT systems. The very high efficiency and low standby consumption WLAN/Bluetooth modules and IoT systems. The very high efficiency and low standby consumption **Single Output** The R-78S is a DC/DC boost converter designed to run from single cell batteries. The input voltage range of 0.65V-3.3V means that alkaline, NiCd, NiMH, zinc-carbon or lithium chemistry cells can be used to generate a stable 1.8V, 3.3V or 3.6V output to power microprocessors, WLAN/Bluetooth modules and IoT systems. The very high efficiency and low standby consumption WLAN/Bluetooth modules and IoT systems. The very high efficiency and low standby consumption can be used to extend battery lifetimes until the „last gasp“ to get the maximum available energy out of the cell. The wide operating temperature of -40°C to +100°C, short circuit protection, OTP, Class A EMC and 3-year warranty round off this high performance converter. |Selection Guide<br>Part<br>Input<br>Output<br>Output<br>Efficiency(1)<br>Max.
