20-50 W High Efficiency DC-DC Converters
* High efficiency topology, 91% typical on EXB50-48S05J * Industry standard footprint * Wide operating temperature -40 C to +70 C (natural convection) * 60% to 110% output trim * No minimum load * Overvoltage and overtemperature protection * Remote sense compensation * Remote ON/OFF * Available RoHS compliant
The EXB50 series of 50 Watt single-output isolated dc-dc converters are specifically designed to meet the power needs of low-voltage silicon. Housed in an open-frame package with an industry-standard footprint, these latest-generation converters offer efficiencies as high as 91%. The series comprises three 24 V input models with 5 V, 3.3 V and 2 V outputs, and six 48 V input models with 12 V, 5 V, 3.3 V 2.5 V, 2 V and 1.8 V outputs. All models feature a wide input range, trimmable output voltage and a 10 A current rating (except the 12 V). Remote sense and remote ON/OFF facilities are included as standard, and the converters are comprehensively protected against overcurrent, overvoltage and overtemperature conditions.
All specifications are typical at nominal input, full load at 25 C unless otherwise stated

Notes
Measured as per recommended set-up. 150 mV pk-pk for EXB5048S12J. 2 di/dt = 0.1 A/s, Vin = 24/48 Vdc, Tc = 25 C, load change = 0.5 lo max. to 0.75 lo max. and 0.75 lo max. to 0.5 lo max. 3 The EXB50 meets level A and level B conducted emissions only with external components connected before the input pins to the converter. 4 Recommended input fusing is a 6.3 A HRC 200 V rated fuse on the 24 V and 3.15 A HRC 200 V rated fuse on the 48 V. 5 This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. 6 Simulated source impedance of 12 H. 12 H inductor in series with +Vin. 7 Start-up into resistive load. 8 EXB50-24S2V0J model has 5.0% max. deviation and 300 s recovery. 9 Maximum output deviation is 10% inclusive of trim. 10 Contact factory for operation at higher altitude. 11 See Application Note 113 for derating curves. CAUTION: Hazardous internal voltages and high temperatures. Ensure that unit is not user accessible. 1
Notes Continued
12 Wide operating temperature on the EXB50-24S05J is -40 C to +60 C. 13 Input transient (48 V) ETS300 132-2 ETR283. 14 100 V, 100 ms transient applies to the EXB50-24S3V3J and the EXB5048S3V3J models. Please add the suffix 'R03' to the model number e.g. EXB50-48S3V3R03J. This is also active low remote ON/OFF. 15 Active low remote ON/OFF available. Please add suffix '-R' to model number e.g. EXB50-48S3V3-RJ. 16 The `J' suffix indicates that these parts are Pb-free (RoHS 6/6) compliant. TSE RoHS 5/6 (non Pb-free) compliant versions may be available on special request, please contact your local sales representative for details. 17 NOTICE: Some models do not support all options.
