from a 0.9-V to 1.8-V input voltage (one alkaline, Ni Cd, or Ni MH battery). Only five small 1-µF ceramic capacitors are required to build a complete high efficiency dc/dc charge pump converter. To achieve the high efficiency over a wide input voltage range, the charge pump automatically selects between a 3x or 4x conversion mode. typical application circuit
