RECOM Power's R420 has been designed for auxiliary power, from 4 mA to 20 mA loops, and other low-power budget applications that require a maximum input current of less than 3.6 mA. This low-profile SMD converter delivers a regulated, short-circuit protected output that can be adjusted between 1.8 V and 5 V with a single external resistor and delivers three times the output current of equivalent linear regulators to power microprocessors, data-loggers, and HART digital modems without affecting the analog 4 mA to 20 mA signal. The R420 will also find many applications in energy scavenging and indoor solar-powered circuits.
