Applications include 48V-powered datacom and telecom installations, base stations, cellular dataphone repeaters, instruments and embedded systems. Wideband output ripple and noise is a low 100 mV, peak-to-peak. The RBQ’s synchronous-rectifi er topology with line regulation and fi xed frequency operation means excellent effi ciencies up to 96%, enabling “no heatsink” operation for most applications up to +85° Celsius (with derating airfl ow). “No fan” or zero airfl ow higher temperature applications may use the optional base plate for cold surface mount- ing or natural-convection heatsinks. A wealth of electronic protection features include input undervoltage lockout (UVLO) , output current limit, short circuit hiccup, and overtemperature shutdown. Available options include positive or negative logic remote On/Off control, conformal coating, and various pin lengths. Assembled using ISO-certifi ed automated surface-mount techniques, the RBQ series is certifi ed to all UL and IEC emis- sions, safety and fl ammability standards.
