DESCRIPTION
The MP1530 combines a triple output step-up
converter with linear regulators to provide a
complete DC/DC solution. It is designed to
power TFT LCD panels from a regulated 3.3V
or 5V supply.
This
fixed-frequency step-up converter with positive
and negative linear regulators. The step-up
converter switch node drives two charge
pumps, which supply powers to their respective
linear regulators. The positive and negative
linear regulator inputs can withstand up to 38V
and down to -20V, respectively.

a
1.4MHz
A single on/off control enables all 3 outputs.
The outputs are internally sequenced at startup
for ease of use. An internal soft-start prevents
input overload at startup. Cycle-by-cycle current
limiting reduces component stress.
The MP1530 is available in a tiny 3mm x 3mm,
16-pin QFN package or a 16-pin TSSOP
package.
