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.

PMP7977 — 适用于 Artix 7 的模拟解决方案
该 Artix 7 电源管理参考设计板使用电源模块、线性稳压器和兼容 PMBus 的系统控制器来提供 FPGA（包括 DDR 存储器终端）所需的所有内核和辅助电压。数字电源图形用户界面用于监控电路板电源轨的电压和电流强度。
TIDEP0011 — 具有动态电压调节功能的 C667x DSP AVS 内核 (CVDD) 的电源解决方案
该参考设计的目标是在 Keystone 多核 DSP（主要是 C66x 系列）中提供 AVS 内核电源 (CVDD)。C66x 系列使用 SmartReflex 技术，使 DSP 能够控制其电源电压。为满足这一要求，此设计将同步降压转换器 (TPS56121) 与 POL 的电压编程器 (LM10011) 相结合。LM10011 接收来自 DSP 的 6 位或 4 位 VCNTL，并将 TPS56121 的输出电压更改为 DSP 所需的电压。LM10011 具有高精度 (1.0%)，从而为其余电源元件和配电提供额外的系统裕度。对于需要特定初始启动电压的处理器，可将 LM10011 配置为以 (...)
