Eighth-Brick Series S i ngl e outp u t DC/DC CONVERTERS High Current, High y, Low 1 • Ultra-high e ciency topology NEW Product • Industry standard eighth brick footprint (identical to quarter-brick pinout) • Low pr through-hole version • Low pr with 38% space savings over other quarter-brick brick converters • Wi de ambient temperature range, -40 ºC to +85 ºC • 80% to 110% output trim • Monotonic start-up in normal and prebiased loads • Basic insulation system • Overvoltage and overtemperature protection • Secondary side control, no optocouplers, fast transient response • 100 V, 100 ms input voltage transient rated • Available RoHS compliant This is a new high e ciency, open-frame, low pr single board, isolated dc-dc converter series in an industry standard eight-brick footprint that provides up to 100 W of output power. The series delivers very high output current at low voltages, and excellent useable power for today’s high performance applications. The series features an input voltage range of 18 Vdc to 36 Vdc and 36 Vdc to 75 Vdc and is available with output voltages of 1.2 V, 1.5 V 1.8 V, 2.5 V, 3.3 V and 5.0 V. The output voltage is adjustable from 80% to 110% of the nominal value. The series also has a remote ON/OFF capability. Overcurrent, overvoltage and overtemperature protection features are included as standard. Full international safety approval 2 YEAR WARRANTY including EN60950-1 VDE and UL/cUL60950, reduces compliance costs and time to market. All are typical at nominal input, full load at 25 °C ambient unless otherwise stated SPECIFICATIONS OUTPUT SPECIFICATIONS EMC CHARACTERISTICS Voltage adjustability 80% to 110% Immunity: ESD air enclosure EN61000-4-2 8 kV/6 kV(O/P within spec.)
