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  
1% Voltage Tracking Between Dual-ch  
600mV Feedback Voltage with ±1% Accuracy  
270us Soft Start Time  
Input DC Current Limit Protection  
Output Over Voltage Protection  
Output Under Voltage Protection  
Input UVLO Protection  
Over Temperature Protection  
Available in a QFN-10 (1.4mm×1.8mm)  
Package  
The MP5610 features as programmable output,  
fixed 1.2MHz switching frequency and rich  
protection modes, like input-output disconnection  
protection, cycle-by-cycle current limit protection,  
thermal shutdown protection, Output over voltage  
protection and Output under voltage protection.
