Convertor answers ATCA carrier card
demands
The PQ60120QEA25 12V bus convertor is ideally suited for designers working to the Advanced Telecom Computing Architecture standards being developed by PICMG.
SynQor reckons the PQ60120QEA25 12V bus convertor raises the bar in terms of performance levels in this category, and is ideally suited for designers working to the Advanced Telecom Computing Architecture (ATCA) standards being developed by PICMG Overcoming some of the limitations of traditional bus convertors, this open frame quarter brick sised device (58.4 x 36.8mm) has a wide input range of 35-75V and produces a fully regulated 12V output capable of supplying up to 25A of payload power to the ATCA carrier card to feed downstream point of load convertors in an IBA (intermediate bus architecture) approach

60W dual-output convertor needs no heatsink
DualQor dual-output industry-standard quarter-brick-sized isolated DC/DC convertors from SynQor are capable of delivering up to 60W at 5 and 3.3V, with no need for an attached heatsink.
Convertor produces 40A from a quarter brick
SynQor has introduced a 40A quarter-brick-sized isolated DC/DC convertor.
The convertor also lends itself to other applications needing high power 12V IBA, as well as to fan tray applications.
SynQor has been able to achieve groundbreaking efficiency levels in excess of 96%, which were previously only available from narrow input "bus convertor" type devices.
This exceptional level of efficiency remains stable from 25 to 100% load, meaning that power dissipation can be optimised across a very wide power range - an important consideration for ATCA carrier card designs employing multiple AMC slots.
The 300W maximum power rating, and the exceptional derating performance of this open frame device means that the existing limitation of 200W dissipation per carrier card specified in the ATCA standards can comfortably be provided up to 85C ambient temperature, with only 1m/s of airflow.
It also enables board designers to exceed the existing 200W level if their needs dictate it and system level cooling allows.
The PQ60120QEA25 is capable of withstanding transients on the input to 100V for 100ms, and has a basic isolation level from input to output of 2250V DC.
Control and protection features include remote sense, a very wide output voltage trim range of -50% to +5%, input undervoltage lockout, output OVP, current limit, short circuit protection, and thermal shutdown.
Operating temperature range is -40 to +100C.
Sample and production quantities are available immediately with a stock to 8-week lead-time.
The modules are priced at $69.00 in OEM quantities. Request a free brochure from SynQor Europe ...
