Abstract
A method is provided for soft starting a single inductor multiple output (SIMO) power supply. The method includes selecting operation in a pulse width modulation (PWM) mode. A first pulse frequency modulation (PFM) mode is enabled to supply a first load with a first voltage and the power supply begins to ramp up the output voltage. After the output voltage has reached a desired value in the PFM mode, the PFM mode is disabled. Then, operation is enabled in the PWM mode. The SIMO power supply then supplies a current to one or more loads in the PWM mode.
