3 Description
The TLV61225 device provides a power-supply solution for products powered by either a single-cell or 2-cell alkaline or Ni MH, or 1-cell Li-primary battery. Possible output currents depend on the input-tooutput 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...
