General Description

The LP6288 is a multi-channel Converter provides six regulated voltage, it includes a boost and three bucks regulators, VGH and VGL charge pump for TFT LCDs. All output are programmable by IIC. VAVDD boost and VHAVDD buck for the Source Driver and the Gamma Buffer, VIO buck and VCORE buck for T-CON, VGH and VGL dual charge pump for the Gate Driver or the Level Shifter. VGH rail can be temperature compensated with GIP technology. Otherwise, High Voltage Stress Mode(HVS) for VAVDD and VHAVDD and the integrated VAVDD Isolation Switch is implemented. VCORE, VHAVDD, VGH, VGL, GPM and the VGH temperature compensation can be enabled and disabled by IIC programming. Other features include short circuit protection, thermal shutdown protection and under-voltage lockout (UVLO). The LP6288 is available in a space saving QFN-40 (0.5mm pitch) package.

总体描述

LP6288是一款多通道转换器，可提供六种调节电压，它包括一个升压和三个降压调节器、用于TFT LCDs的VGH和VGL电荷泵。所有输出均可由IIC编程。VAVDD升压和VHAVDD降压用于源极驱动器和伽马缓冲器，VIO降压和VCORE降压用于T-CON，VGH和VGL双电荷泵用于栅极驱动器或电平转换器。VGH轨道可以用GIP技术进行温度补偿。否则，VAVDD和VHAVDD以及集成式VAVDD隔离开关将采用高压应力模式（HVS）。IIC编程可以使能和禁用VCORE、VHAVDD、VGH、VGL、GPM和VGH温度补偿。其他功能包括短路保护、热关断保护和欠压锁定（UVLO）。LP6288采用节省空间的QFN-40（0.5毫米间距）封装。
