MP5610
2.7V to 5.5V Input, 1.2MHz, Dual-ch
LCD Bias Power Supply
FEATURES
DESCRIPTION
2.7V-to-5.5V Input Voltage
The MP5610 is a dual-output converter with
2.7V-to-5.5V input for small size LCD panel bias
supply. It uses peak-current mode to regulate the
positive output voltage and uses a negative
charge pump to provide negative output voltage.
The MP5610 has very good efficiency
performance because the negative charge pump
draws power directly from the positive converter
switching node which can save power loss much.
Also, MP5610 provides good voltage tracking
between positive and negative output by well
matching the internal MOSFET on resistance
value. The fully integrated synchronous
rectification increases total efficiency and
reduces PCB space requirements.
Max. 50mA Output Current for Each Output
Up to Programmable 5.8V Output Voltage
0.5% Line Regulation for Step-up Converter
0.5% Load Regulation for Step-up Converter
