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 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 MP1530 is available in a tiny 3x3mm, 16-
pin QFN package or a 16-pin TSSOP package.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance θ
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P
D
(MAX) = (T
J
(MAX)-T
A
)/θ
JA
. Exceeding the maximum allowable powe
r
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on approximately 1” square of 1 oz copper.
