Eighth-Brick Series Single output DC/DC CONVERTERS High Current, High y, Low 1 NEW Product • • • • • • • • • • Ultra-high e ciency topology 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 including EN60950-1 VDE and UL/cUL60950, reduces compliance costs and time to market. All 2 YEAR WARRANTY SPECIFICATIONS are typical at nominal input, full load at 25 °C ambient unless otherwise stated OUTPUT SPECIFICATIONS EMC CHARACTERISTICS Volta ge a djus ta bility 8 0 % to 1 1 0 % M inimum loa d Overshoot 0% At turn-on and turn-o None U nd e r s ho o t N o ne Transient response (S e e N ote 1 ) 60 mV to 150 mV typ. deviation 2 0 µs re c ove ry 24 V nominal 48 V nominal Input c urre nt N o loa d Remote OFF Active high remote ON/OFF Logic compatibility ON OFF Undervoltage Lockout 24 Vin 48 Vin 48 Vin Start-up time (See Note 2) 18-36 Vdc 36-75 Vdc 5 0 mA 5 mA Open collector ref to -input O pe n c irc uit or >2 . 4 V dc <0 . 4 V d c Power up Power down Power up Power down Power up Remote ON/OFF 17.5 V (typ.) 16.5 V (typ.) 35.5 V (typ.) 33.5 V (typ.) 15 ms (typ.) 15 ms (typ.)
