MP5600
Compact Multiple-Output
Power Supply for TV-LCD panel
The Future of Analog IC Technology
DESCRIPTION
FEATURES
The MP5600 represents an integrated power
supply for large size LCD panel. It contains a
buck regulator to generate the logic supply rail,
a boost regulator to generate the source driver
supply, two charge-pump controllers to
generate a positive output and negative output
respectively, and a programmable delay gate
pulse management switch. Each regulator
features adjustable output, internal soft-start,
and timer-delayed fault protection.

With the input range from 9V to 18V, the buck
regulator can adjust output from 1.5V to 5V; the
boost regulator can adjust output from Vin to
19.5V. Both the buck and boost regulators use
an external-selectable fixed-frequency (450 kHz
or 675 kHz).

With external diode, two regulated charge pump
controller could afford voltage up to 3X boost
output and low to negative boost output. Gate
pulse management provides TFT positive gate
driver voltage with two operation mode and
programmable delay.
The MP5600 has a 5V linear regulator, a
1.227V reference output, adjustable power up
sequences, and over temperature protection.
