1 / 24 page  The DRQ 500W series provides a fully regulated, digitally controlled DC output in a ¼-brick format that will support the evolving Advanced Bus Con- verter (ABC) industry standard footprint for isolated board mounted power modules. The DRQ series supports advances in power conversion technology including a digital interface supporting the PMBus protocol for communications to power modules. The DRQ series offers high output current (up to 43.5 Amps) in an industry standard “quarter brick” package. The DRQ series is an isolated, regulated, 500W-11.5Vout quarter brick that supports the TNV input voltage range of 38V-75V with a typical efficiency of 95.5%. Advanced automated surface mount assembly and planar magnetics deliver galvanic isolation rated at 2250 Vdc for functional insulation. Target markets include networking equipment, Power over Ethernet applications, wireless networking equip- ment, telecommunications equipment, wireless pre-amplifiers, industrial and test equipment, and applications requiring a regulated 11.5V output. A wealth of self-protection features include input undervoltage lockout and overtemperature shut- down; over current protection using the “hiccup” autorestart technique provides indefinite short- circuit protection, along with output OVP. The DRQ series is certified to safety standards UL/IEC/CSA 60950-1, 2nd edition. It meets RFI/EMI conducted emission compliance to EN55022, CISPR22 with an external filter.
