The charge pump provides backlight current in conjunction with four matched current sinks. The load and supply conditions determine whether the charge pump operates in 1x, 1.5x, or 2x mode. An optional fading feature that gradually adjusts the backlight current is provided to simplify control software. The SC624A also provides two low-dropout, low-noise linear regulators for powering a camera module or other peripheral circuits. The SC624A uses an I2C compatible serial interface. The interface controls all functions of the device, including backlight current and two LDO voltage outputs. |
