EXA40 Series Single output DC/DC CONVERTERS 40W High Efficiency DC/DC Converters 1 * High efficiency topology, 91% typical at 5V * Approved to EN60950, UL1950, CSA C22.2 No. 234/950 * Operating ambient temperature of -40C to +70C (natural convection) * 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 The EXA40 Series, comprising 8 different models is targeted specifically at the telecommunications, industrial electronics, mobile Telecommunications and distributed power markets. The series offers two wide input voltage ranges of 18-36VDC and 36-75VDC. Typical efficiencies are 91% for the 5V output, 88% for the 3.3V, 86% for the 2.75V and 84% for the 1.8V. The series has been designed primarily for Telecommunications applications and complies with ETS 300 386-1 immunity and emission standards for high priority of service class. In addition the series complies with ETS 300 019-1-3 environmental standards (all classes) including shock, vibration, humidity and thermal performance. A high level of reliability has been designed into all models through the extensive use of conservative derating criteria. Remote enable and overtemperature shutdown are included as standard while true latching OVP is available as an option. 2 YEAR WARRANTY SPECIFICATIONS All specifications are typical at nominal input, full load at 25C unless otherwise stated OUTPUT SPECIFICATIONS Voltage adjustability 2V75, 3V3, 5V outputs 1V8 output Line regulation Low line to high line Load regulation Full load to no load Output current range MINIMUM TYPICAL MAXIMUM 10% +12/-17% 11% +13/-18% 12% +14/-19% +0.05% +0.4% +0.20% +0.4% 0A 8A Ripple and noise 20MHz bandwidth 20MHz bandwidth 50mV pk-pk 10mV rms Temperature coefficient See Figure 4 0.01%/C OVP transient (See Note 6) 5V output 3V3/2V75 outputs 1V8 output 6.8V TVS 4.1V TVS 4.1V TVS OVP latching (See Notes 1, 3) (optional) 5V output 3V3 output 2V75 output 1V8 output Short circuit protection (Note 5) Continuous Short circuit current (Note 5) Rshort <20m 10A rms Transient response Peak deviation Settling time 50% to 75% and back to 1.0%, no external cap 100mV 250s 150mV 400s Current limit Low line to high line 140% 180% 1.0% 1.5% 6.0V 4.0V 3.4V 2.4V 100% Voltage accuracy INPUT SPECIFICATIONS Input voltage range 24Vin nominal 48Vin nominal Input current No load Remote OFF, UVLO Inrush current ETS 300 132-2 UVLO turn ON voltage (Note 4) UVLO turn OFF voltage (Note 4) All inputs All inputs Start-up time Nominal line 6.2V 4.2V 3.6V 2.5V 100mV pk-pk 20mV rms 0.02%/C 6.4V 4.4V 3.8V 2.6V 12A rms MINIMUM TYPICAL 18VDC 36VDC 24VDC 48VDC 36VDC 75VDC 50mA 2.5mA 100mA 4mA 88% 77% MAXIMUM 94% 86% 100% 94% 50ms 100ms File Name: LF_EXA40.PDF Rev: 15 Jan 2002 EXA40 Series Single output DC/DC CONVERTERS 40W High Efficiency DC/DC Converters 2 For the most current data and application support visit www.artesyn.com/powergroup/products.htm INPUT SPECIFICATIONS ON OFF Remote ON/OFF source current INPUT VOLTAGE 18-36VDC 18-36VDC 18-36VDC 18-36VDC 36-75VDC 36-75VDC 36-75VDC 36-75VDC MINIMUM TYPICAL 1.0V 4.5V 2.5V -70A Active low, control to -Vin, open collector input Open circuit voltage OUTPUT VOLTAGE (2) 1.5 to 2.0V 2.5 to 3.0V 3.0 to 3.6V 4.5 to 5.5V 1.5 to 2.0V 2.5 to 3.0V 3.0 to 3.6V 4.5 to 5.5V NOMINAL OUTPUT VOLTAGE 1.8V 2.75A 3.3V 5.0V 1.8V 2.75V 3.3V 5.0V Radiated emissions ESD air ESD contact Surge (500V) Fast transients Radiated immunity Conducted immunity 1 EN55022, internal filter and 4.7F film cap EN55022, external filter, EN55022 (See Design Note) EN61000-4-2, level 3 EN61000-4-2, level 4 EN61000-4-5, level 3,4 EN61000-4-4, level 3,4 EN61000-4-3, level 3 EN61000-4-6, level 3 Level A Level B Level B 2 3 4 5 6 7 GENERAL SPECIFICATIONS Efficiency Basic insulation Input fuse 24V Input fuse 48V Switching frequency Approvals and standards (See Notes 1, 7, 8, 9) Weight MTBF, See Design Note See table 1500VDC 3.5A slow blow 2.0A slow blow Fixed 300kHz (See Notes 1, 7, 8, 9) EN60950 Bi-national UL1950 CSA C22.2 No. 234/950 Input/output (See Note 8) MIL-HDBK-217 MAXIMUM 5.5V -100A TYPICAL EFFICIENCY 84% 87% 88% 90% 84% 86% 88% 91% MODEL NUMBER (1) EXA40-24S1V8 EXA40-24S2V75 EXA40-24S3V3 EXA40-24S05 EXA40-48S1V8 EXA40-48S2V75 EXA40-48S3V3 EXA40-48S05 Notes EMC CHARACTERISTICS (Continued) ETS 300 386-1 table 5 Conducted emissions (See Design Note 101) OUTPUT CURRENT (MAX.) 8.0A 8.0A 8.0A 8.0A 8.0A 8.0A 8.0A 8.0A 25g (0.88 oz) 250,000 hours ENVIRONMENTAL SPECIFICATIONS Thermal performance Operating ambient -40C to +70C, temperature See curves Non-operating -55C to +105C Over temperature Loss of Function 75C to +85C shutdown Self-Recovery (LFS) ETS 300 019-2-3 Classes T3.1 to T3.5 Air temperature Low: IEC 68-2-1 -40C High: IEC 68-2-2 +70C Change: IEC 68-2-1 -40C to +70C Relative humidity IEC 68-2-56 10% to 100% RH IEC 68-2-30 Condensation Vibration, Class 3M5 IEC68-2-6 2 to 9 Hz, 3mm disp. 9 to 200Hz 1g MIL-STD-202F Method 204 cond.
