    摘要: Electronic devices with a VCOM display panel are configured to provide a common voltage VCOM to a VCOM display panel backplane, referred to as a VCOM reference plane. The common voltage is supplied by a VCOM application circuit coupled to the VCOM reference plane. The VCOM application circuit includes a linear amplifier, such as a Class AB amplifier, coupled to a switched transient assist circuit configured to output the common voltage. The switched transient assist circuit stabilizes the amplifier in the presence of large transient output currents but with minimized power dissipation and heat rise in the amplifier.
