DC/DC CONVERTERS 10W DC/DC Converters 1

2 YEAR WARRANTY

  • 4:1 input voltage range
  • Approved to EN60950, UL1950, CSA C22.2 No. 950
  • Operating ambient temperature of -40°C to +70°C in still air
  • High demonstrated reliability with conservative component deratings
  • Complies with ETS 300 019-1-3/2-3
  • Complies with ETS 300 132-2 input voltage and current requirements
  • Fully compliant with ETS 300 386-1
  • Pin compatible with NFC10 and BXA10 series
  • Basic insulation system (input to output) The CXA10 series comprising of five different models delivers single and dual output voltages covering 3.3V, 5V, 12V, ±5V, ±12 and ±15V. The series has a wide 4:1 input voltage range of 18 to 75VDC. The CXA10 has been designed as a competitive open-frame alternative for the communications market. The product is supplied in the industry standard footprint of 2.0 x 1.0 x 0.394 inches. Other product features include overvoltage protection, short circuit protection and remote on/off. All components are placed in a fully automated environment. Planar magnetics are used in the design to improve the reliability and reduce the profile of the DC/DC converter. The series has full international safety approval to EN60950 and UL1950 reducing system compliance costs, and it has a basic insulation system from input to output making it suitable for a wide variety of applications. All specifications are typical at nominal input, full load at 25°C unless otherwise stated EMC CHARACTERISTICS ETS 300 386-1 table 5 Conducted emissions EN55022 (See Note 6) Level A EN55022, external filter, Level B VDE0878, 48V models Radiated emissions See Application Note 100 ESD air EN61000-4-2, level 3 ESD contact EN61000-4-2, level 4 Surge (500V) EN61000-4-5, level 3, 4 Fast transients EN61000-4-4, level 3, 4 Radiated immunity EN61000-4-3, level 3 Conducted immunity EN61000-4-6, level 3 GENERAL SPECIFICATIONS Efficiency See table Isolation voltage Input/output test voltage 1500VDC Switching frequency Fixed 400kHz Approvals and standards EN60950, UL1950 (See Notes 7,8,9,10,11) CSA C22.2 No. 950 Material flammability UL94V-0 Weight 12g (0.42 oz) MTBF MIL-HDBK-217F 456,621 hours (Representative model Parts stress method 48S05 @ 48Vin) Ground Benign @ 25°C ENVIRONMENTAL SPECIFICATIONS Thermal performance Operating ambient -40°C to +70°C, temperature See curves Non-operating -55°C to +105°C ETS 300 019-2-3 Classes T3.1 to T3.5 Air temperature Low: IEC 68-2-1 -40°C High: IEC 68-2-2 +70°C Change: IEC 68-2-14 -40°C to +70°C Relative humidity IEC 68-2-56 10% to 100% RH IEC 68-2-30 Condensation Vibration, Class 3M5 IEC68-2-6 2 to 9Hz, 3mm disp. 9 to 200Hz 1g MIL-STD-202F Method 204 cond.
