PTH05050Y 用于 DDR/QDR 存储器的 6A 输出 5V 输入的总线终端电源模块
PTH05050Y 描述
The PTHxx010Y 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 15 A of current (12 A for 12-V input) 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.
Both the PTHxx010Y series employs an actively switched synchronous rectifier output to provide state-of-the-art stepdown switching conversion. The products are small in size
