The TPS54260-Q1 device is a 60-V, 2.5-A, step-down regulator with an integrated high-side
MOSFET. Current mode control provides simple external compensation and flexible component
selection. A low ripple pulse skip mode reduces the no load, regulated output supply current to 138
µA. Using the enable pin, shutdown supply current is reduced to
1.3-µA, when the enable pin is low.
Under voltage lockout is internally set at 2.5 V, but can be increased using the enable pin. The output voltage startup ramp is controlled by the slow start pin that can also be configured for sequencing and tracking. An open drain power good signal indicates the output is within 94% to 107% of the nominal voltage.
A wide switching frequency range allows efficiency and external component size to be optimized. Frequency fold back and thermal shutdown protects the part during an overload condition.
The TPS54260-Q1 is available in 10-pin thermally-enhanced HVSSOP and 10-pin 3-mm × 3-mm VSON package.

TIDA-00322 — 汽車超音波液位/品質量測參考設計
TI 參考設計 TIDA-00322 是一款汽車液位與液體識別測量系統。它基於雙通道 TDC1000-Q1 超音波 AFE 和即時微控制器 C2000。此參考設計也可搭配 TDC1000 使用，用於工業/消費應用。此解決方案支援具反向電池防護的 4.5-40 V 系統功能。
對於原型設計和訊號可存取性來進行產品開發，TI 建議使用 TDC1000-C2000EVM 作為汽車設計的硬體評估平台。對於工業或消費類設計，建議使用 TDC1000-TDC7200EVM 開始評估。此 EVM 能夠使用 MSP430 或 TDC7200 作為計時器；每個的使用狀況取決於應用的飛時測距準確度需求。
