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 -40°C to +70°C (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 All specifications are typical at nominal input, full load at 25°C unless otherwise stated SPECIFICATIONS OUTPUT SPECIFICATIONS MINIMUM TYPICAL MAXIMUM Voltage adjustability 2V75, 3V3, 5V outputs ±10% ±11% ±12% 1V8 output +12/-17% +13/-18% +14/-19% Line regulation Low line to high line +0.05% +0.4% Load regulation Full load to no load +0.20% +0.4% Output current range 0A 8A Ripple and noise 20MHz bandwidth 50mV pk-pk 100mV pk-pk 20MHz bandwidth 10mV rms 20mV rms Temperature coefficient See Figure 4 ±0.01%/°C ±0.02%/°C OVP transient (See Note 6) 5V output 6.8V TVS 3V3/2V75 outputs 4.1V TVS 1V8 output 4.1V TVS OVP latching (See Notes 1, 3) 5V output 6.0V 6.2V 6.4V (optional) 3V3 output 4.0V 4.2V 4.4V 2V75 output 3.4V 3.6V 3.8V 1V8 output 2.4V 2.5V 2.6V Short circuit protection (Note 5) Continuous Short circuit current (Note 5) Rshort <20mW10A rms 12A rms Transient response Peak deviation 50% to 75% and back 100mV 150mV Settling time to 1.0%, no external cap 250μs 400μs Current limit Low line to high line 100% 140% 180% Voltage accuracy ±1.0% ±1.5% INPUT SPECIFICATIONS MINIMUM TYPICAL MAXIMUM Input voltage range 24Vin nominal 18VDC 24VDC 36VDC 48Vin nominal 36VDC 48VDC 75VDC Input current No load 50mA 100mA Remote OFF, UVLO 2.5mA 4mA Inrush current ETS 300 132-2 UVLO turn ON voltage (Note 4) All inputs 88% 94% 100% UVLO turn OFF voltage (Note 4) All inputs 77% 86% 94% Start-up time Nominal line 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 MINIMUM TYPICAL MAXIMUM Remote ON/OFF Active low, control to -Vin, open collector input ON Open circuit voltage 4.5V 5.5V OFF 1.0V 2.5V Remote ON/OFF source current -70μA -100μA INPUT OUTPUT NOMINAL OUTPUT TYPICAL MODEL (2) (1) VOLTAGE VOLTAGE OUTPUT VOLTAGE CURRENT (MAX.)
