System and method for dual mode DC-DC power conversion

摘要

A dual-mode power saving dc-dc converter. The dual-mode power saving dc-dc converter has a first switch control circuit and a second switch control circuit. The first switch control circuit is connected to a first current sensor, and the second switch control circuit is connected to a second current sensor. The two current sensors are connected to a control logic, which is operable to enable and disable the first and second switch control circuit. The first switch control circuit uses less power than the second switch control circuit. The control logic activates the first switch control circuit during low current load and activates the second switch control circuit used during high current load. Other systems and methods are disclosed.
