DC/DC Converter
R-78S
Description
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
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.
