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

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

load regulation, an output remote sense is also provided. Package options include both throughhole and surface

mount configurations.
