The TPS6122x family devices provide 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.
