Description

The PTH12050Y is 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 PTH12050Y 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 PTH12050Y series employs an actively switched synchronous rectifier output to provide state of the art stepdown switching conversion. The PTH12050Y products are small in size and are an ideal choice where space, performance and high efficiency are desired.
