Description

Often a regulated DC output voltage is needed between the minimum and maximum input voltages of a DC/DC converter but neither a buck or boost converter in standard configurations is sufficient. However a boost converter integrated circuit (IC) can be configured to drive a single-ended primary inductor converter (SEPIC) power stage and provide an output voltage that is between the input voltage
