The PTHxx060Y 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 TT output that will source or
sink up to 10 A of current to accurately track their V REF input. V TT is the required bus
termination supply voltage, and V REF is the reference voltage for the memory and chipset
bus receiver comparators. V REF is usually set to half the V DDQ power supply voltage.
The PTHxx060Y 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.
