[ 2 YEAR WARRANTY ]
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/in
3
. 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.

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.
5
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.
