Lowpowersemi LP6284
The LP6284 includes a high-performance boost regulator, a low dropout linear regulator (LDO), a gate pulse modulator (GPM), a voltage detector, a VCOM buffer (unity-gain OPA), and a VGH charge pump controller for active matrix TFT LCDs. The converter is a high switching frequency (640kHz or 1.2MHz) current-mode regulator with an integrated 16V N-Channel 0.2Ω MOSFET that allows the use of ultra-small inductors and ceramic capacitors. It provides fast transient response to pulsed loading while achieving efficiency over 90%.| Part No. | LP6284 |

GENERAL DESCRIPTION
The low-dropout (LDO) linear regulator can supply up to 350mA current while input voltage is 3.3V. It is suitable for the supply voltage of the timing controller. The Unity-Gain buffer can drive the LCD VCOM voltage that features high short-circuit current, fast slew rate and rail-to-rail inputs and outputs. The VGH charge pump controller provides regulated TFT Gate-On voltage. The regu
