RBQ-12/33-D48xB-C www.murata-ps.com Quarter-Brick 400-Watt Isolated DC-DC Converters Output (Vout, typ) Current (A) Nominal Input (V) 11.7 33 48 Typical unit FEATURES PRODUCT OVERVIEW „„ 386 Watts total output power, 11.7 VDC @ 33 A The fully isolated (2250 Vdc) RBQ-12/33-D48xB-C module accepts a 36 to 75 Volt DC input voltage range (48 VDC nominal) and converts it to a low Vdc output. 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. „„ Regulated Intermediated Bus Architecture (RIBA) with PoL converters „„ 96% ultra-high efficiency at full load (typical) „„ 36 to 75 Volt DC input range (48 VDC nominal) „„ Standard quarter-brick footprint „„ Synchronous rectifier topology with 100 mV ripple & noise „„ Up to +85° Celsius thermal performance (with derating) „„ Stable no-load operation „„ Multiple-unit parallel operation for increased current „„ Fully isolated to 2250 VDC (BASIC) The RBQ’s synchronous-rectifier topology with line regulation and fixed frequency operation means excellent efficiencies up to 96%, enabling “no heatsink” operation for most applications up to +85° Celsius (with derating airflow). “No fan” or zero airflow higher temperature applications may use the optional base plate for cold surface mounting 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-certified automated surface-mount techniques, the RBQ series is certified to all UL and IEC emissions, safety and flammability standards. „„ Remote On/Off enable control „„ Extensive protection features – SC, OC, UVLO, OT „„ Certified to full safety, emissions and environmental standards „„ Approved to UL 60950-1, CAN/CSAC22.2 No. 60950-1, IEC60950-1, EN60950-1 safety approvals (2nd Edition, with Amendment 1) F1 Isolation Barrier +Vin (1) +Vout (8) • Switching External DC Power Source On/Off Control (2) Open = On Closed = Off (Positive logic) • Filters Controller and Power Transfer Duty Cycle Regulation • Current Sense Reference and Error Amplifier -Vin (3) -Vout (4) Figure 1.
