MPQ1530DQ-AEC1-LF-Z Datasheet, PDF (1/15 Pages) MPS Industries, Inc. – Triple Output Step-Up Plus Linear Regulators for TFT Bias AEC-Q100 Qualified

DESCRIPTION
The MPQ1530 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 device integrates a 1.4MHz
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 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 MPQ1530 is available in a tiny 3x3mm, 16-
pin QFN package.
