TPS61222MDCKTEP

增强型产品：具有 5.5μA 静态电流的低输入电压、0.7V 升压转换器 6-SC70 -55 to 125

The TPS61222 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. The device is offered in a 6-pin SC-70 package DCK measuring 2 mm × 2 mm to enable small circuit layout size.
