Designed to provide the highest efficiency on-board 12V output for telecom, computing and server applications it comes with optional digital control.
With efficiency rated over 97 percent, 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 60V, making it suitable for 48V data centre and communications network equipment.
Rated for up to 110 amps, the 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 minimised using large diameter pins.
The module can operate between minus 400C and 850C 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 information.
