www.ti.com PTH03050Y PTH05050Y PTH12050Y SLTS221A * MARCH 2004 * REVISED OCTOBER 2005 6-A NON-ISOLATED DDR/QDR MEMORY BUS TERMINATIO.
The PTHxx050Y are a series of ready-to-use switching regulator modules from Texas Instruments designed specifically for bus termination in DDR and QDR.
Features
* VTT Bus Termination Output (Output Tracks the System VREF)
* 6 A Output Current (8 A Peak)
* 3.3-V, 5-V or 12-V Input Voltage
* DDR and QDR Compatible
* On/Off Inhibit (for VTT Standby)
* Undervoltage Lockout
* Operating Temperature:
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 bu
