A first mode is a sleep mode and a second mode is a wake-up mode. During the sleep mode, the power supply detects a no-load presence and artificially increases the output voltage Vout to its maximum allowable value. In some embodiments, this is accomplished by pulling up an output of a error amplifier that feeds a PWM module. During the wake-up mode when the power supply wakes up from the sleep mode under maximum load, the output voltage Vout sinks from the artificially higher voltage, but still stays above a minimum operational voltage level. A slew rate compensation can be implemented to control a rate at which the output voltage drops when a load is applied. The artificially high output voltage during no-load condition and the slew rate compensation provide open loop voltage adjustment."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"No load detection and slew rate compensation","description":"The power regulation control circuit is implemented during two modes.
