This document introduces a series of switching regulator modules designed by Texas Instruments for bus termination in DDR and QDR memory applications. These modules feature high efficiency, VTT bus termination output, output overcurrent protection, and 15A output current.
The PTHxx010Y series are ready-to-use switching regulator modules designed specifically for bus termination in DDR and QDR memory applications. Operating from 3.3-V, 5-V, or 12-V inputs, these modules generate a Vcc output that sources or sinks up to 15 A of current (12 A for 12-V input) to accurately track the Vref input voltage.
Key features include efficiencies up to 91%, output overcurrent protection with auto-reset, and on/off inhibit functionality for standby power savings. The modules are available in both through-hole and surface-mount configurations and meet various safety agency approvals including UL/cUL60950.
| Output Current (3.3V/5V Input) | 15 A |
|---|---|
| Output Current (12V Input) | 12 A |
| Efficiency | Up to 91% |
| Input Voltage Range (PTH12010Y) | 10.8 V to 13.2 V |
| Operating Temperature Range | -40°C to 85°C |
| Switching Frequency (PTH12010Y) | 200 kHz to 300 kHz |
The module sources or sinks up to 12 A of current when using a 12-V input.
The modules can source or sink up to 15 A of current, except for the 12-V input version which provides 12 A.
Applying a low-level ground signal to this input turns off the output voltage, V+.
