The TPS84320RUQ is an easy-to-use integrated power solution that combines a 3-A DC/DC converter with power MOSFETs, an inductor, and passives into a low profile, BQFN package. This total power solution allows as few as 3 external components and eliminates the loop compensation and magnetics design process.

The 9×15×2.8 mm BQFN package is easy to solder onto a printed circuit board and allows a compact point-of-load design with up to 95% efficiency and excellent power dissipation with a thermal impedance of 13°C/W junction to ambient. The device delivers the full 3-A rated output current at 85°C ambient temperature without airflow.

The TPS84320 offers the flexibility and the feature-set of a discrete point-of-load design and is ideal for powering performance DSPs and FPGAs. Advanced packaging technology afford a robust and reliable power solution compatible with standard QFN mounting and testing techniques.

TIDEP0011 — 具有動態電壓調節的 C667x DSP AVS 核心 (CVDD) 電源解決方案

此參考設計旨在為 Keystone 多核 DSP(主要是 C66x 系列)中的 AVS 內核電源 (CVDD) 供電。C66x 系列使用 SmartReflex 技術使 DSP 能夠控制其電源電壓。為了滿足此要求,此設計將同步降壓轉換器 (TPS56121) 與 POL 的電壓編程器 (LM10011) 結合在一起。LM10011 可以接受來自 DSP 的 6 位元或 4 位元 VCNTL,並將 TPS56121 的輸出電壓變更為 DSP 所需的電壓。LM10011 具有高準確度 (1.0%),可在其餘電源供應元件和配電中增加額外的系統裕度。對於需要特定初始啟動電壓的處理器,LM10011 (...)
