General Description
The G1588 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 con-
verter 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 ap-
plications.
G1588 can also be used as a stand-alone level shifter.
Connecting SHD to GND can disable whole boost
function, shut down function, temperature compensa-
tion function, UVP, OCP except for XON function.
G1588 features extensive protection functions that in-
clude UVLO, OVP, UVP, OCP and OTP. The device
operates over the temperature range of -40°C to +85°C.
G1588 is available in a 5mmx5mm 40-lead TQFN
Package.
