The TPS50601A-SP is a radiation hardened, 7-V, 6-A synchronous step-down converter, which is optimized for small designs through high efficiency and integrating the high-side and low-side MOSFETs. Further space savings are achieved through current mode control, which reduces component count, and a high switching frequency, reducing the inductor’s footprint. The devices are offered in an ultra small, thermally enhanced 20-pin ceramic flatpack package.

The output voltage startup ramp is controlled by the SS/TR pin which allows operation as either a stand alone power supply or in tracking situations. Power sequencing is also possible by correctly configuring the enable and the open drain power good pins. In addition, the TPS50601A-SP can be configured in master-slave mode to provide up to 12-A of output current.

Cycle-by-cycle current limiting on the high-side FET protects the device in overload situations and is enhanced by a low-side sourcing current limit which prevents current runaway. There is also a low-side sinking current limit which turns off the low-side MOSFET to prevent excessive reverse current. Thermal shutdown disables the part when die temperature exceeds thermal shutdown temperature.

TIDA-010191 — 航太級多通道 JESD204B 15-GHz 時脈參考設計

相位陣列天線和數位波束成形技術,是提高未來航太雷達成像和寬頻衛星通訊系統的性能的關鍵技術。數位波束成形與類比波束成形不同,通常每個天線元件需要一套資料轉換器。這些轉換器需要具有具體定義相位關係的時鐘。此參考設計展示如何透過已定義及可調整相位關係,產生低雜訊 MHz 至 GHz 時脈訊號。在發生單一事件後,甚至可能恢復時脈階段。透過操作兩個 ADC12DJ3200QML-SP 評估模組,及在 3.2 GHz 時其對應之 FPGA 架構擷取平台,以及 10-ps 板對板偏斜的情況,藉此來展示 JESD204B 支援。
