Multi-Channel DC-DC Converter for LCD Panels



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.
