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. • 9V to 18V Input Voltage Range • 450kHz or 675kHz Selectable Frequency • 7.5V Input Under-Voltage Lockout • High Efficiency • Internal Soft-start Buck Regulator • Peak Current-Mode, Fast Transient Response • Integrated 20V, 5A, 60mΩ N-MOSFET • Internal Fixed 3.3V or Adjustable Output Voltage • Power Good Signal • Short Circuit Protection with Switching Frequency Fold-Back Boost Regulator • Peak Current-Mode Control • Integrated 20V, 5A, 60mΩ N-MOSFET • 19.5V Over Voltage Protection • Full Isolation Between VIN and Load • 100mΩ MOSFET Output Isolation Switch • Adjustable Positive Charge Pump and Negative Charge Pump regulator with 120mA Max Load 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. 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. • • • • • Adjustable GPI and GPO Delay Time Dual Mode, Logic-Controlled, High-Voltage Switch with Programmable Delay Internal Timer-Delay Fault Protection 150°C Thermal Shutdown 40-Pin, 5mm x 5mm, Thin QFN Package APPLICATIONS • LCD TV Panel • LCD Monitor “MPS” and “The Future of Analog IC Technology” are Trademarks of Monolithic Power Systems, Inc.

The maximum allowable continuous power dissipation at any ambient temperature is calculated by PD (MAX) = (TJ (MAX)-TA)/θJA. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. Internal thermal shutdown circuitry protects the device from permanent damage. 3) The device is not guaranteed to function outside of its operating conditions. 4) Measured on JESD51-7, 4-layer PCB. www.MonolithicPower.com MPS Proprietary Information.
