Abstract
A high-voltage power converter with a high-side switch coupled with a high-voltage input and a high-side switch control coupled with the high-side switch are presented. The high-side switch control drives the high-side switch on and off. There is a low-side switch coupled via an output node to the high-side switch. The low-side switch is on when the high-side switch is off and vice versa. A supply capacitor is coupled with a low-voltage supply terminal. The high-side switch control to provides a supply voltage for the high-side switch control. A communication module is coupled with the high-side switch control to provide a bidirectional communication between the high-side switch control and a control system that operates in a low-voltage domain, wherein the communication to and from the high-side switch control is enabled when the low-side switch is on and the high-side switch is off.
