Abstract

The disclosure is directed to implementing a gradual power transition, in digital and mixed-signal power converters. A 'soft start' smooths an abrupt power change in the output of a power converter such as when the power converter starts up after turning on the power to a device. A power converter may receive a digital control signal that includes a command to start up, as well as includes a power level set point. This disclosure includes a circuit that receives the digital control signal and outputs a modified control signal to the power converter that causes the power converter to gradually change the power output of the power converter until the power output reaches the power level set point. The circuit dynamically determines a step size, length of time of each step and other parameters based on characteristics of the input digital control signal.
