DESCRIPTION
The MP1531 is a triple output step-up converter
with charge-pumps to make a complete DC/DC
converter to power a TFT LCD panel from a
2.7V to 5.5V supply.
The MP1531 includes a 250KHz fixed frequency
step-up converter and a positive and negative
linear regulator. The linear regulators are
powered via charge-pumps driven by the step-up
converter switch node.
A single on/off control enables all 3 outputs.
The outputs are internally sequenced at
power-on for ease of use. An internal soft-start
prevents overloading the input source at
startup. Cycle-by-cycle current limit reduces
component stress.
The MP1531 is available in both a tiny 16-pin
QFN package (3mm x 3mm) and a 16-pin
TSSOP package.
