BUCK CONVERTER |
摘要 |
A buck converter is described having a buck converter output for outputting an output supply voltage; a first power supply domain operably coupled to a power source; a second power supply domain; a power supply controller coupled to the first power supply domain, the second power supply domain and the buck converter output; wherein the power supply controller is configured to supply power to the second power supply domain from the first power supply domain or the buck converter output, in dependence of the buck converter output supply voltage. Changing the current supplied to the second power supply domain to the buck converter output may reduce the quiescent current consumption from a battery power source, prolonging battery life. |
