PTH12050Y Datasheet 6-A NON-ISOLATED DDR/QDR MEMORY BUS TERMINATION MODULES

Manufacturer: Texas Instruments

General Description

The PTHxx050Y are a series of ready-to-use switching regulator modules from Texas Instruments designed specifically for bus termination in DDR and QDR memory applications.

Operating from either a 3.3-V, 5-V or 12-V input, the modules generate a VTT output that will source or sink up to 6 A of current (8 A transient) 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.
