0.33W DC/DC converter, input 0.65...3.15V, output 3.3V/100mA, SIP4

The R-78S is a DC/DC boost converter designed for single battery operation. The input voltage range of 0.65V-3.3V means that alkaline, NiCd, NiMH, zinc-carbon or lithium-chemical 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 life to the "last breath" to extract the maximum available energy from the cell. The wide operating temperature range of -40°C to +100°C, short-circuit protection, OTP, Class A EMC and 3-year warranty round off this high-performance converter.
