HPQ-8.3/22-D48 Series www.murata-ps.com Isolated 22-Amp Quarter Brick DC-DC Converters PRODUCT OVERVIEW The HPQ-8.3/22-D48 series offers high output systems needing controlled startup/shutdown, an current (up to 22 Amps) in an industry standard external remote On/Off control may use either posi- quarter brick package requiring no heat sink for tive or negative polarity. Remote Sense inputs com- most applications. The HPQ-8.3/22-D48 series de- pensate for resistive line drops at high currents. livers fixed 8.3 Vdc output at 183 Watts for printed A wealth of self-protection features avoid prob- circuit board mounting. Wide range inputs on the lems with both the converter and external circuits. Typical unit 2.3 x 1.45 x 0.4 converter are 36 to 75 Volts DC These include input undervoltage lockout and (48 Volts nominal), ideal for datacom and telecom overtemperature shutdown using an on-board tem- systems. The fixed output voltage is regulated to perature sensor. Overcurrent protection using the FEATURES within 0.25%. hiccup autorestart technique provides indefinite Advanced automated surface mount assembly short-circuit protection. Additional safety features 8.3 Volts DC fixed output up to 22 Amps and planar magnetics deliver galvanic isolation include output overvoltage protection and reverse Industry standard quarter brick 2.3 x 1.45 x rated at 2250 Vdc for basic insulation.
