The CXCO4331 integrated one VGON boost converter with a high voltage level shifter. This device is suitable for GOA TFT-LCD panel applications. The VGON boost converter is a current mode regulator with a temperature compensation feature. The output voltage is adjusted according to the voltage on the VT pin (temperature reading) and the voltage level is set by voltage reference on the END pin. This boost converter has an integrated 45V/1.3Ω NMOS switch and a fixed 600kHz switching frequency. It provides fast transient response to pulsed loading while achieving efficiency over 85%. The level shifters transform the logic-level controlled signals, which are generated by the display timing controller (TCON), into the high-level signals needed by LCD panel. Different CKH1~6 output patterns will be generated by different external settings. Each channel of level shifter output uses low impedance transistors to achieve fast rising and falling time, even when driving the capacitive loads present in LCD applications. CXCO4331 can also be used as a stand-alone level shifter. Connecting SHD to GND can disable whole boost function, shut down function, temperature compensation function, UVP, OCP except for XON function. CXCO4331eatures extensive protection functions that include UVLO, OVP, UVP, OCP and OTP. The device operates over the temperature range of -40°C to +85°C. CXCO4331s available in a 5mmx5mm 40-lead TQFN Package.
