MP5610GQG-P Monolithic Power Systems

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 Max. 50mA Output Current for Each Output 2.7V-to-5.5V input for small size LCD panel bias Up to Programmable 5.8V Output Voltage supply. It uses peak-current mode to regulate the positive output voltage and uses a negative 0.5% Line Regulation for Step-up Converter charge pump to provide negative output voltage. 0.5% Load Regulation for Step-up Converter The MP5610 has very good efficiency 1% Voltage Tracking Between Dual-ch performance because the negative charge pump 600mV Feedback Voltage with 1% Accuracy draws power directly from the positive converter 270us Soft Start Time switching node which can save power loss much. Input DC Current Limit Protection Also, MP5610 provides good voltage tracking Output Over Voltage Protection between positive and negative output by well Output Under Voltage Protection matching the internal MOSFET on resistance Input UVLO Protection value. The fully integrated synchronous Over Temperature Protection rectification increases total efficiency and Available in a QFN-10 (1.4mm1.8mm) reduces PCB space requirements. Package The MP5610 features as programmable output, APPLICATIONS fixed 1.2MHz switching frequency and rich protection modes, like input-output disconnection Feature Phones and Smart Phones protection, cycle-by-cycle current limit protection, Small Size LCD Displays thermal shutdown protection, Output over voltage All MPS parts are lead-free, halogen free, and adhere to the RoHS directive. For protection and Output under voltage protection. MPS green status, please visit MPS website under Quality Assurance.
