An important extension to its
Giga family of Eighth Brick dc/dc converters has been announced
by power conversion specialists SynQor,
with the addition of a 75W/12V output device capable of delivering
up to 6.25A of output current.
Ideally suited to power downstream POL converters in Intermediate
Bus Architecture (IBA) applications, the PQ60120EGL07 converter
offers 91% efficiency, low power dissipation and high reliability.
This is achieved using synchronous rectification, together with
SynQor's patented topology to achieve extremely high efficiency.
This single-board, open-frame package has industry standard pin-out
and footprint, and covers the full Telecom input voltage range of
35-75V. It can supply its full rated output current of 6.25A at
up to 55°C ambient, with just 200LFM (1m/s) of forced air-cooling.
Accordingly, it may be used in applications in which only Quarter
Brick packages could previously meet the power requirements.
Capable of withstanding input transients of up to 100V/100ms, the
PQ60120EGL07 incorporates basic isolation from input to output of
2000Vdc. Control and protection features include remote sense, input
UVLO, output voltage trim (+10%/-20%) output OVP, current limit,
short circuit, and thermal shutdown. Sample and production quantities
are available immediately, with a stock to 8- week lead-time.
