EXA40 Series Single output .. DC/DC CONVERTERS 40W High Efficiency DC/DC Converters - 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) - plies with ETS 300 019-1-3/2-3 - plies with ETS 300 132-2 input voltage and current requirements - Fully pliant with ETS 300 386-1 The EXA40 Series, prising 8 different models is targeted specifically at the telemunications, industrial electronics, mobile Telemunications 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 Telemunications applications and plies with ETS 300 386-1 immunity and emission standards for high priority of service class. In addition the series plies 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 25°C unless otherwise stated OUTPUT SPECIFICATIONS Voltage adjustability Line regulation Load regulation Output current range Ripple and noise Temperature coefficient OVP transient (See Note 6) 20MHz bandwidth 20MHz bandwidth See Figure 4 5V output 3V3/2V75 outputs 1V8 output 5V output 3V3 output 2V75 output 1V8 output Continuous Rshort <20mΩ 50% to 75% and back to 1.0%, no external cap Low line to high line 100% 10A rms 100m V 250µs 140% ±1.0% MINIMUM 24Vin nominal 48Vin nominal No load Remote OFF, UVLO ETS 300 132-2 All inputs All inputs Nominal line 88% 77% 94% 86% 50ms 100% 94% 100ms File Name: LF_EXA40.PDF Rev: 15 Jan...
