Since battery capacity is limited in any portable electronic device, power minimization is crucial. DC-DC converters must dissipate minimal energy to extend battery run-time. Power management schemes are used in most low-power hardware:Unused circuitry is powered-down and gated clocks are employed to reduce powerconsumption during idle mode ,Such techniques may present severe load variations (up to several orders of magnitude), and the system may idle for a large fraction of the overall run-time. This implies the need for a high conversion efficiency not only under full load, but over a large load variation. Furthermore, in the ultra-low-power applications common to portable systems, the quiescent operating power (control power) of the regulator must be kept to an even lower level to ensure that it does not contribute significantly to the overall dissipation. For example, a multimedia chipset has been demonstrated in [Chandrakasan94a] which supports speech I/O, pen input and full motion video, and consumes less than 5 mW at 1.1 V. The control circuit for a converter supplying this chipset must have substantially lower quiescent power.
