    Hello Sam,

    What is the requirement for the input supply? Do you have the max specification for the LCD bias part?
    The LCD bias with integrated LED driver solutions we have do not exactly fit to your requirements but I would recommend the TPS65154. It can provide AVDD, VGH, VGL and you can use the VCOM in a follower configuration for the DVDD rail.
    The WLED driver can provide up to 240 mA if you combine all current sinks.

    Another solution would be to combine the LCD bias IC TPS6510x or TPS6514x (www.ti.com/.../tps65145.pdf ; www.ti.com/.../tps65105.pdf) with an LED driver.

    Best regards,
    Diaara
