MP5600

Compact Multiple-Output Power Supply for TV-LCD panel

Datasheet

Description

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 670 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.
The MP5600 is available in a 40 pins, 5mm x 5mm, thin QFN package. The device operates over the -20°C to +85°C temperature range.
