More Information
Summary:A power supply including a first converter configured to convert an input voltage into a first output voltage; a second converter configured to convert the first output voltage into a second output voltage; a first feedback circuit configured to output a first pulse width modulation (PWM) signal to the first converter to control a level of the first output voltage; and a mode controller configured to compare the input voltage and a reference voltage and determine whether the first converter operates in a first mode or a second mode based on the compared result. When the input voltage is less than or equal to the reference voltage, the first converter boosts the input voltage and output the boosted voltage as the first output voltage in the first mode, and when the input voltage is greater than the reference voltage, the first converter bypasses the input voltage and output the bypassed voltage as the first output voltage in the second mode.
