BXA40-48S2V9-SM

BXA40 Series DC/DC CONVERTERS Single output 40W Wide Input DC/DC Converters 1 • Pin-compatible with NFC40 Series • Meets telecom power supply interface standard ETS300-132-2 • EN60950, CSA C22.2 No. 950 and UL1950 safety approvals • EN61000-4-2, -3, -4, -5, -6 immunity compliant • Fixed frequency operation at 350kHz typ. • MTBF in excess of 500,000 hours • Basic insulation system with 1500V isolation • Remote sense on low voltage logic outputs • Output voltage trim The BXA40 Series providing up to 40 Watts, has been conceived as an applications specific range of DC/DC converters, specifically addressing telecommunications, industrial electronics, test equipment, mobile telecommunications and distributed power applications. The series offers two wide input voltage ranges, 18-36VDC and 36-75VDC, and is available with single outputs from 2.9V to 12V. The BXA40 series is designed to meet ETSI telecoms interface standards ETS300-132-2. Together with internal filtering, safety approval to IEC950 and basic insulation, the 48VDC models are ideal for telecommunications applications. The 24V models are particularly suited to industrial and test equipment applications, featuring EN61000-4-2, -3, -4, -5 and -6 immunity compliance. Other features include low output ripple, overvoltage protection, indefinite short circuit protection, remote enable and remote sense. All specifications are typical at nominal input, full load at 25°C unless otherwise stated 2 YEAR WARRANTY SPECIFICATIONS OUTPUT SPECIFICATIONS Voltage adjustability Line regulation Load regulation Ripple and noise (20MHz bandwidth) Low line to high line Full load to no load 2.9V and 3.3V 5V 12V All models ±10% ±0.3% ±1.0% 30mV pk-pk 50mV pk-pk 100mV pk-pk 20mV rms ±0.02%/°C (See Note 9) (See Note 10) 25% to 100% load (See Note 11) 135% Vout Continuous 4.0% EMC CHARACTERISTICS Conducted emissions Radiated emissions ESD air ESD contact Surge Fast transients Radiated immunity Conducted immunity EN55022, FCC part 15, (See Notes 4 and 13) EN55022, FCC part 15 EN61000-4-2, level 3 EN61000-4-2, level 4 EN61000-4-5, level 3 EN61000-4-4, level 3 EN61000-4-3, level 3 EN61000-4-6, level 3 Level B Level A criteria 1 criteria 1 criteria 1 criteria 1 criteria 1 criteria 1 Perf.
