Control circuit and method for a soft-start scheme of a switch mode power supply for a power amplifier |
摘要 |
There is provided a control circuit including a sampling controller configured to sample an output voltage of a power converter at an appropriate time slot by opening a control loop. A soft-start circuit configured to enable soft-starting of an internal soft-start reference voltage to start from the sampled output voltage and to control the internal soft-start reference voltage to a predetermined target value in order to pre-charge the output voltage close to an input voltage level, or to continue charging the output voltage to a predetermined output voltage value.
