SPECIFICATIONS
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 VTT output that will
source or sink up to 6 A of current to accurately track their VREF input. VTT is the
required bus termination supply voltage, and VREF is the reference voltage for the
memory and chipset bus receiver comparators. VREF is usually set to half the VDDQ
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.
