The TLV61225 device provides a power-supply solution for products powered by either a single-cell or 2-cell alkaline or NiMH, or 1-cell Li-primary battery. Possible output currents depend on the input-to-output voltage ratio. The boost converter is based on a hysteretic controller topology using synchronous rectification to obtain maximum efficiency at minimal quiescent currents. The output voltage of this device is set internally to a fixed output voltage of 3.3 V. The converter can be switched off by a featured enable pin. While being switched off, battery drain is minimized. The device is offered in a 6-pin SC-70 package (DCK) measuring 2 mm × 2 mm to enable small circuit layout size.

TIDA-00670 — 低成本且靈活的電壓監(jiān)控器和電池測試儀參考設計

這是一種低成本的靈活電壓監(jiān)控器，它使用電壓參考來測試電池電壓。該解決方案也可用作電壓軌監(jiān)測器，適用于需要具有多電壓軌的精確供電的許多應用。通過使用 TI 的超低功耗電壓參考，不僅能降低總系統(tǒng)功耗，還能維持較低的 BOM 成本。測試和顯示電池電壓可提供示例來表明對此進行設計并在類似的應用中進行實施是多么容易。
