PTH05010Y的产品详情：

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 V_TT output that will source or sink up to 15 A of current (12 A for 12-V input) 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 PTHxx010Y series employs an actively switched synchronous rectifier output to provide state-of-the-art stepdown switching conversion. The products are small in size (1.37 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 V_TT 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.
