The DRQ-11.4/88-L48NB-C regulated converter module deliver a 11.2V output @ Vin = 48Vdc in a quarter brick open frame package at astonishing efficiency. The fully isolated (1500Vdc) DRQ-11.4/88-L48NB-C series accept a 36 to 60 Volt DC input voltage range and converts it to a low Vdc output that drives external point-of-load (PoL) DC-DC power converters such as Murata Power Solutions’ tiny Okami series which feature precise regulation directly at the load. Applications include datacom and telecom installations, cellular dataphone repeaters, base stations, instruments and embedded systems. Wideband output ripple and noise is typical 100mV, peak-to-peak. The DRQ’s synchronous-rectifier topology and fixed frequency operations means excellent efficiencies up to 96.3%. A wealth of electronic protection features include input under voltage lockout, over voltage lockout protection, output current limit, current sharing, short circuit hiccup, Vout overshoot, and over temperature shutdown. Available options include various pin lengths and the baseplate. Assembled using ISO-certified automated surface-mount techniques, the DRQ series is designed to meet all UL and IEC emissions, safety and flammability certifications.
