Abstract
A chip-on-glass (COG) display driver comprises a direct current to direct current converter (DC-DC) converter that uses “off-glass” and/or “off-chip” inductive/capacitive (LC) components. The DC-DC converter can be configured to use either an internal or external switch (such as a power FET) in response to a mode signal. Selection of an internal or external mode allows a single converter chip design to be optimized for various applications.
