DESCRIPTION
The PTHxx060Y 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
V
input. V
is the required bus termination supply voltage, and V
REF
TT
and chipset bus receiver comparators. V
Both the PTHxx060Y series employs an actively switched synchronous rectifier output to provide state-of-the-art
stepdown switching conversion. The products 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 V
bus to be turned off to save power in a standby mode of operation. To ensure tight
TT
load regulation, an output remote sense is also provided. Package options include both throughhole and surface
mount configurations.

I + Inhibit 47 µF 220 µF CAPACITOR RECOMMENDATIONS FOR THE PTH03060Y AND PTH05060Y DDR POWER MODULES (3.3-V/5-V OPTION) Input Capacitor The recommended input capacitor(s) is determined by the 330 µF minimum ripple current rating. Ripple current and less than 160 mΩ equivalent series resistance (ESR) values are the major considerations, along with temperature, when designing with different types of capacitors. Unlike polymer tantalum, regular tantalum capacitors have a recommended minimum voltage rating of 2 × ...
