Abstract

A power supply system can include at least one power switch to generate an output current based on an input voltage in response to a switching signal to generate an output voltage. A feedback system generates a feedback current based on the output voltage. A mode detector generates a control current associated with the output current based on the feedback current and selects between a pulse-width modulation (PWM) mode and a pulse mode based on an amplitude of the control current. The PWM mode is associated with a sequential on-time and off-time of the at least one power switch, and the pulse mode is associated with adding an idle time between the on-time and the off-time of the at least one power switch based on the switching signal. A gate driver system generates the switching signal based on the mode.
