With an input operating range of 4V to 14V, both commonly used LCD-TV input supplies, 5V and 12V, are supported. An AVDD supply up to 20V is generated by a high-performance PWM BOOST converter with an integrated 4.4A FET. VON is generated using an integrated charge pump with on-chip diodes and can be modulated using an on-chip VON slice control circuit. VOFF is generated using an integrated charge pump controller. Additionally, the chip allows for two logic supplies. A buck regulator with an included 2.5A high side switch is used for the main logic output and an internal LDO controller can be used to generate a second logic LDO output. To facilitate production test, an integrated HVS circuit is included which can provide high voltage stress of the LCD panel. ...
