Title: DC-DC REGULATOR AND SOFT-START CONTROL METHOD THEREFOR, AND CONTROLLER
Abstract:
A DC-DC regulator and soft-start control method therefor, and a controller. The method can implement quick soft-start of a DC-DC regulator, thereby improving the response speed of a system. The soft-start control method for a DC-DC regulator comprises: a controller determines a current power supply state of a DC-DC regulator, wherein the power supply state is battery powered or non-battery powered (S601); the controller controls, according to the power supply state, the working state of the LDO module in the DC-DC regulator and the working state of the DC-DC module in the DC-DC regulator, so that the DC-DC regulator outputs a required voltage value (S602).
