DIPMODULE (EUU)-6-314.2008 mm² 23.12 x 13.59

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 V_TT output that will source or sink up to 6 A of current (8 A transient) to accurately track their V_REF input. V_TT is the required bus termination supply voltage, and V_REF is the reference voltage for the memory and chipset bus receiver comparators. V_REF is usually set to half the V_DDQ power supply voltage.

Both the PTHxx050Y series employs an actively switched synchronous rectifier output to provide state-of-the-art step-down switching conversion. The products are small in size (0.87 in × 0.5 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 V_TT bus to be turned off to save power in a standby mode of operation.

Package options include both through-hole and surface mount configurations.
