BXA200 SERIES Single output • • • • • • • • The BXA200 Series of high density DC/DC converters uses Artesyn Technologies patented resonant transition zero voltage switching topology together with advanced packaging to provide high performance with a power density of 36Watts/in3. Fixed frequency operation at 500kHz together with our unique integrated magnetics and internal filters, facilitate easier system filtering, limiting input conducted noise to EN55022 level A. Zero voltage switching together with advanced power train design minimizes power losses, yielding efficiencies up to 85%, from a 4.6 x 2.4 x 0.5 inch industry standard package. The BXA200 series with six single output models from 3.3V to 48V, offer short circuit protection, overvoltage protection, true current sharing, redundancy and up to 40A capability, all of which simplify and accelerate design-in cycles, reduce component counts, save PCB space and increase system reliability, giving you the lowest overall cost of ownership with the shortest possible time to market.

BAND (2) A 10µF tantalum capacitor on the output. Specified for all conditions line and load. Fit external 1KΩ resistor in series with remote on/off pin. Normal operation: When a high impedance power source is used, an aluminium electrolytic capacitor of value 220µF rated at 100V should be placed across the two voltages input pins, –Vin and +Vin. This capacitor should be located as close as possible to the input terminals. Remote sense operation: Remote sense will automatically compensate for output voltage line losses up to 0.5VDC. The unit will operate if the sense terminals are left open. There are internal resistors between each sense line and the output terminal. However, regulation will degrade if the sense lines are left open. Do not reverse the sense leads as this may damage the unit. External trimming: The modules allow a trim range of ±10% of the output voltage to the rated maximum power. Trimming is implemented as shown. Synchronization function: This function allows the synchronisation of the fixed switching frequency to an external clock. The frequency adjustability range is 500kHz ±35kHz and the synch. function is TTL compatible, coupled through a 1nF capacitor. Two or more units can be synchronized to each other by connecting all of the synch. pins together. Parallel and N+I redundancy operation: Parallelling: Two or more units can be paralleled to give higher power operation. The power output will be a multiple of the power block. Diodes are not necessary for parallel operation. N+I Redundancy: If redundancy is required, isolating diodes should be used. In this set-up when one unit is turned off, it will disconnect itself from the sharing group and the other unit(s) will take up the extra load. 9 Thermal performance: The baseplate must be kept below 85°C during normal operation. This can be achieved by providing the proper amount of moving air coupled with the proper size heatsink. The thermal impedance in still air with no heatsink is 5.0°C/W. If the baseplate temperature exceeds 100°C, the thermal protection circuitry protects the module by decreasing the current limit setpoint. 10 With a 120µF capacitor across the input terminals. 11 Contact your local distributor. 12 This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product.
