Abstract
A universal serial bus (USB) charger provides power to a client device. A USB connector interfaces with a client device and receives a request for the output voltage of the USB charger to be at a specific value. If the requested voltage level is lower than the current output voltage level, the output voltage level is set to the requested level and a bleeder circuit is enabled to discharge the output capacitor of the USB charger.
