he LP6286HQVF-F is an integrated power supply solution optimized for small to medium size thinfilm transistor (TFT) liquid crystal displays (LCD’s).
The boost converter operates at the frequency of 1.2MHz. The integrated N-channel FET has a typical current limit of 3.5A and can support output voltages up to 18V.
The gate-on and gate-off charge pumps provide regulated TFT-LCD gate-on and gate-off supplies. Both outputs can be adjusted by external resistive voltage-dividers.
The integrated operational amplifier is typically used for LCD VCOM driving; the output can sink or source up to 150mA short-circuit current. This operational amplifier features fast slew rate (25V/us), wide bandwidth (20MHz).
A built-in voltage detector generates a reset signal when the input voltage drops below a specified level. The reset signal is active low, and the detecting level is decided by an external resistor divider.
