Description
DC-DC CONVERTERS Non-isolated DDR/QDR Memory Bus Termination Module
Manufacturer
ARTESYN [Artesyn Technologies]
Datasheet
The PTHxx050Y are a new series of non-isolated dc-dc converters designed
specifically for bus termination in DDR and QDR memory applications. Operating from
either a 3.3 Vdc, 5 Vdc or 12 Vdc input, the modules generate a V
source or sink up to 6 A of current to accurately track their V
required bus termination supply voltage, and V
memory and chipset bus receiver comparators. V
power supply voltage. The PTHxx050Y series employs an actively switched
synchronous rectifier output to provide state of the art stepdown switching conversion.
The products are small in size and are an ideal choice where space, performance and
high efficiency are desired.
All specifications are typical at nominal input, V
unless otherwise stated. C
