POWER SUPPLY SYSTEMS AND METHODS |
摘要 |
Aspects include power supply systems. An error amplifier can generate an error voltage based on feedback associated with an output voltage to a reference voltage. A PWM generator can generate a PWM signal based on the error voltage. A power stage can generate the output voltage based on the PWM signal. The power stage can include a transconductance amplifier that generates a temperature-compensated sense current associated with a magnitude of an output current. An output voltage tuning circuit sets a desired magnitude of the output voltage based on at least one digital signal to adjust the reference voltage and the feedback voltage. An oscillator system generates a clock signal based on repeatedly charging and discharging a capacitor based on the clock signal and a comparator that compares the capacitor voltage and a second voltage having a magnitude that changes based on the state of the clock signal. |
