illustrate

The TPS6030x boost, regulated charge pump produces an output voltage from 0.9-V to 3-V ± 4% or 3.3-V to 4% ± an input voltage of 1.8 V (one alkaline, nickel-cadmium or nickel-metal hydride battery).

Only five small 1 uF ceramic capacitors require a complete high-efficiency DC/DC charge pump converter. For high efficiency over a wide input voltage range, the conversion mode between 3x or 4x of the charge pump is automatically selected.
