WWW.WALLINDUSTRIES.COM1 603 778 2300 UP TO 20 WATTS - DC SERIES SURFACE MOUNT CONVERTER FEATURES:

  • Output trim function
  • Overvoltage protection
  • High efficiency (to 88%)
  • Six sided shield
  • Undervoltage lockout
  • Remote On/Off
  • Short-circuit protection
  • UL/CUL 1950, file #E155800 THE DC SERIES FROM WALL INDUSTRIES The DC surface mount series offers the user a wide input range and single output with tight regulation. These converters are highly reliable and well suited for telecom applications. SPECIFICATIONS: DC SERIES INPUT SPECIFICATIONS (complies with ETS300 132 part 4.4) (nominal Vin at full load) OUTPUT SPECIFICATIONS GENERAL SPECIFICATIONS ENVIRONMENTAL SPECIFICATIONS EMC CHARACTERISTICS Due to advances in technology, specifications subject to change without notice. 3/18/04 All specifications apply at 25° C ambient unless otherwise noted.

NOTES: 1. An external filter capacitor is required for normal operation. The capacitor should be capable of han- dling 1A ripple current. We suggest: Nippon chemi- con KMF series, 220 µF/100V, ESR 90Mohm 2. Simulated source impedance of 12 µH. 12µH inductor in series with +Vin. 3. Remote On/Off is referenced to the negative input (-Vin). 4. Measured with 104pF/50V MLCC. Test conditions: nominal input and full load. 5. BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40ºC. (Ground fixed and controlled environment). 6. We recommend solder paste volume of 2.8 cubic mm (170,000 cubic mills/pin). 7. N/C pins may be used internally by the module and should not be connected by the customer. 3/18/04
