Step-Up Boost DC/DC Converters Integrated Switch, Texas Instruments### 直流/直流开关调节器转换器（集成开关），Texas InstrumentsTexas Instruments 的此系列高度集成的高效开关稳压器包括步升（升压）、步降（降压）、步升/降（增压/降压）和反相类型，为每个直流稳压器应用提供高效的解决方案。

The is a low input voltage Step-up Converter provides a power-supply solution for products powered by either a single-cell, two-cell or three-cell alkaline, NiCd or NiMH or one-cell Li-Ion or Li-polymer 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 the adjustable version can be programmed by an external resistor divider or is set internally to a fixed output voltage. The converter can be switched off by a featured enable pin. While being switched off, battery drain is minimized.
