摘要:
Methods and systems for a multiple output capacitive buck/boost converter are disclosed and may include charging one or more input capacitors via an input voltage. One or more output voltages may be generated on a chip by switching the charged input capacitors to output capacitors via a switch array on the chip. The switch array may be controlled via a state machine. A constant current and/or voltage may be generated for the one or more output voltages via one or more current and/or voltage comparators. A variable resistance may be coupled in series with one or more switches in the switch array. The one or more input capacitors may be discrete capacitors external to the chip and/or integrated within the chip. One or more of the output voltages may be greater than the input voltage, or may be less than the input voltage.
