EXA40 SERIES Single output * 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 [ 2 YEAR WARRANTY ] SPECIFICATION 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 3675VDC. 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. All specifications are typical at nominal input, full load at 25C unless otherwise stated OUTPUT SPECIFICATIONS MINIMUM TYPICAL MAXIMUM 10% +12/-17% 11% +13/-18% 12% +14/-19% Voltage adjustability 2V75, 3V3, 5V outputs 1V8 output 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 20MHz bandwidth 50mV pk-pk 10mV rms Temperature coefficient See Figure No. 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 Current limit Low line to high line 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) All inputs UVLO turn OFF voltage (Note 4) All inputs Start-up time PAGE 1 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 150mV 400s 140% 180% 1.0% 1.5% MINIMUM TYPICAL 18VDC 36VDC 24VDC 48VDC 36VDC 75VDC 50mA 2.5mA 100mA 4mA 88% 77% MAXIMUM 94% 86% 100% 94% 50ms 100ms DC/DC CONVERTERS | 40W DC/DC 40 Watt High efficiency DC/DC converters INPUT SPECIFICATIONS Remote ON/OFF ON OFF Remote ON/OFF source current MINIMUM TYPICAL 1.0V 4.5V 2.5V -70A Active low, control to -Vin, open collector input Open circuit voltage MAXIMUM 5.5V -100A INPUT VOLTAGE OUTPUT VOLTAGE (2) NOMINAL OUTPUT VOLTAGE OUTPUT CURRENT (MAX.)
