PTH12060Y

The PTH12060Y 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 V_TT output that will source or sink up to 10 A of current to accurately track their VREF input. V_TT is the required bus termination supply voltage, and VREF is the reference voltage for the memory and chipset bus receiver comparators. V_REF is usually set to half the VDDQ power supply voltage. Both the PTHxx060Y series employs an actively switched synchronous rectifier output to provide state-of-the-art stepdown switching conversion.

The products PTH12060Y are small in size (1 in × 0.62 in), and are an ideal choice where space, performance, and high efficiency are desired, along with the convenience of a ready-to-use module. Operating features include an on/off inhibit and output over-current protection (source mode only).

The on/off inhibit feature allows the VTT bus to be turned off to save power in a standby mode of operation. To ensure tight load regulation, an output remote sense is also provided. Package options include both throughhole and surface mount configurations.
