The devices are typically powered by two Alkaline, Ni Cd, or Ni MH battery cells and operate down to a minimum supply voltage of 1.6 V. Continuous output current is a minimum of 100 m A from a 2-V input. Only four external capacitors are needed to build a plete low-ripple dc/dc converter. The push-pull operating mode of two single-ended charge pumps assures the low output voltage ripple, as current is continuously transferred to the output.
