Eighth-Brick Series Single output DC/DC CONVERTERS • • • • • • • • • • High Current, High Efficiency, Low Profile NEW Product 1 Ultra-high efficiency topology Industry standard eighth brick footprint (identical to quarter-brick pinout) Low profile through-hole version Low profile with 38% space savings over other quarter-brick brick converters Wide 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 efficiency, open-frame, low profile, 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 including EN60950-1 VDE and UL/cUL60950, reduces compliance costs and time to market. All specifications are typical at nominal input, full load at 25 °C ambient unless otherwise stated Patent No. 6,765,810 Other Patents Pending 2 YEAR WARRANTY SPECIFICATIONS OUTPUT SPECIFICATIONS Voltage adjustability Minimum load Overshoot Undershoot Transient response (See Note 1) INPUT SPECIFICATIONS Input voltage range Input current 24 V nominal 48 V nominal No load Remote OFF 18-36 Vdc 36-75 Vdc 50 mA 5 mA Open collector ref to -input Open circuit or >2.4 Vdc
