The UCD9246 is a multi-rail, multi-phase synchronous buck digital PWM controller designed for non-isolated DC/DC power applications. This device integrates dedicated circuitry for DC/DC loop management with flash memory and a serial interface to support configurability, monitoring and management.
The UCD9246 was designed to provide a wide variety of desirable features for non-isolated DC/DC converter applications while minimizing the total system component count by reducing external circuits. The solution integrates multi-loop management with sequencing, margining, tracking and intelligent phase management to optimize for total system efficiency. Additionally, loop compensation and calibration are supported without the need to add external components.
To facilitate configuring the device, the Texas Instruments Fusion Digital Power Designer is provided. This PC based Graphical User Interface offers an intuitive interface to the device. This tool allows the design engineer to configure the system operating parameters for the application, store the configuration to on-chip non-volatile memory and observe both frequency domain and time domain simulations for each of the power stage outputs.
TI has also developed multiple complementary power stage solutions – from discrete drivers in the UCD7k family to fully tested power train modules in the PTD family. These solutions have been developed to complement the UCD9k family of system power controllers.

TMDSEMU200-U — XDS200 USB 偵錯探測器
XDS200 是為 TI 嵌入式裝置偵錯的偵錯探測器 (模擬器)。與低成本 XDS110 和高效能 XDS560v2 相比，XDS200 是兼具低成本與優異效能的完美平衡，可在單一 pod 中支援各種標準 (IEEE1149.1、IEEE1149.7、SWD)。所有 XDS 偵錯探測器均支援具嵌入式追踪緩衝區 (ETB) 的 Arm® 與 DSP 處理器中的核心和系統追蹤功能。透過針腳進行核心追蹤則需要 XDS560v2 PRO TRACE。
XDS200 透過 TI 20 針腳連接器 (配備適用 TI 14 針腳、Arm Cortex® 10 針腳和 Arm 20 針腳的多重轉接器) (...)
