Asceta™ iQG Series DC/DC Power Modules

48V Input, 12V / 33A Output

Quarter Brick

The Asceta™ power module series provides

exceptionally high true useable power in an

industry standard quarter brick format. With

up to 96% efficiency and a maximum power

rating of 400W, the Asceta series of DC-DC

converters is ideally suited for tight space,

power-hungry, ATCA applications in

demanding thermal environments. This

rugged building block is designed to serve as

the core of your high reliability system. The

droop current sharing capability allows

multiple modules to be connected in parallel.

The monotonic start-up into a pre-bias output

capability with the synchronous rectification

enhances versatility.

Data Sheet: Asceta iQG Series –Single Output Quarter Brick TM Thermal Management: An important part of the overall system design process is thermal management; thermal design must be considered at all levels to ensure good reliability and lifetime of the final system. Superior thermal design and the ability to operate in severe application environments are key elements of a robust, reliable power module. A finite amount of heat must be dissipated from the power module to the surrounding environment.
PAGE 12
Data Sheet: Asceta iQG Series –Single Output Quarter Brick TM performance page for the power module of interest. In all conditions, the power module should be operated below the maximum operating temperature shown on the derating curve. For improved design margins and enhanced system reliability, the power module may be operated at temperatures below the maximum rated operating temperature. Heat transfer by convection can be enhanced by increasing the airflow rate that the power module experiences.
PAGE 13
Data Sheet: Asceta iQG Series –Single Output Quarter Brick TM Operating Information: Over-Current Protection: The power modules have current limit protection to protect the module during output overload and short circuit conditions. During overload conditions, the power modules may protect themselves by entering a hiccup current limit mode. The modules will operate normally once the output current returns to the specified operating range. A latched overcurrent protection option is also available.
