Supports 48-volt data centre and network applications
Artesyn Embedded Power, an advanced energy company, has announced the BDQ1300, a new 1300 watt quarter-brick dc-dc converter, designed to provide the highest efficiency onboard 12V output for telecom, computing and server applications, with optional digital control. With efficiency rated over 97 per cent, the BDQ1300 is designed as a voltage source for non-isolated point-of-load converters. It can accept an input voltage range from 40 to 60 volts, making it ideal for 48-volt data centre and communications network equipment.
Rated for up to 110 amps, the Artesyn BDQ1300 is a fully isolated dc-dc converter,
which can be applied with separate input and output ground connections. This isolation
means that EMI management and any possible fault condition can be contained within
the primary side of the converter. The modules use a standard high-current quarter-brick
pin-out. A pair of power pins are provided for the positive output and ground connections
to enable the current to be conducted to the host PCB. Conduction losses from the
module are minimized using large-diameter pins.
“The BDQ1300 has been designed to primarily support two power-conversion
architectures,” said Andy Brown, director of technical marketing dc-dc for Artesyn
Embedded Power. “Either the conventional and widely used ‘two-stage’ conversion
architecture network, where the BDQ1300 only provides power to non-isolated, 12V
input point-of-load converters such as Artesyn’s LGA80D or LGA50D families; or the
module can also be used to support a hybrid conversion architecture. This is where
some of the application’s power is converted with 48 V to low-voltage ‘direct conversion’
products, such as those being developed by members of the Power Stamp Alliance, and
– operating alongside this direct conversion network – a conventional two-stage
The module can operate between minus 40 degrees Celsius and 85 degrees Celsius
with air cooling, and it offers options for base plate cooling.
The BDQ1300 is available without the four-pin PMBus connection, which gives a
solution of maximum conversion performance with minimum control complexity. The
four-pin PMBus header provides standard PMBus control and monitoring functions such
as voltage and current monitoring, start-up and shutdown control, protection feature
warning and shutdown limits, temperature monitoring functions and revision-control
The BDQ1300 is available from Artesyn’s global network of sales representatives,
distributors and value added resellers.
