DC DC Switching Controllers
PMIC (Power Management Integrated Circuit) DC to DC switching controllers are voltage regulation ICs used in high efficiency circuits configured to generate output supply voltages above (boost or step-up) or below (buck or step-down) the input supply. Other topologies may include; buck-boost, flyback, forward, cuk, SEPIC, full bridge, half bridge, and push-pull. They differ from linear regulators that require minimum voltages and "burn off" excess voltage.
