RT4831 is a multifunctional device that can provide power to the LCD display
|
|
and LCD backlight.
|
|
|
|
For Display Bias Voltage DSVP and DSVN, the output range is about 4V to 6.5V.
|
|
It is sufficient to meet the current LCD power requirement.
|
|
|
|
DSVLCM is a boost regulator in IC internal as DSVP and DSVN input power.
|
|
Its voltage should be configured above 0.15V to 0.2V gap larger than the
|
|
voltage needed for DSVP and DSVN. Too much voltage gap could improve the
|
|
voltage drop from the heavy loading scenario. But it also make the power
|
|
efficiency worse. It's a trade-off.
