OPERATION
The MP1531 is a step-up converter with two
integrated linear regulators to power TFT LCD
panels. Typically the linear regulators are
powered from diode charge-pumps driven from
the switch node (SW). The user can set the
positive charge-pump to be a doubler, tripler, or
quadrupler to achieve the required linear
regulator input voltage for the selected output
voltage. Typically the negative charge-pump is
configured as a 1x or 2x inverter.
