MP2212 16V, 3A, 600kHz Synchronous Step-Down Converter The Future of Analog IC Technology DESCRIPTION FEATURES The MP2212 is an internally compensated 3A Output Current 600kHz fixed frequency PWM synchronous Input Supply Range: 3V to 16V step-down regulator. With a 3V to 6V bias 80m Internal Power MOSFET Switches supply (V ), MP2212 operates from a 3V to CC All Ceramic Output Capacitors Design 16V input and generates an adjustable output Up to 95% Efficiency voltage from 0.8V to 0.9xV at up to 3A load IN 600kHz Fixed Switching Frequency current. Adjustable Output from 0.8V to 0.9xV IN The MP2212 integrates an 80m high-side Internal Soft-Start switch and an 80m synchronous rectifier for Frequency Synchronization Input high efficiency without an external Schottky Thermal Shutdown diode. With peak current mode control and Cycle-by-Cycle Current Limiting internal compensation, it is stable with a Hiccup Short Circuit Protection ceramic output capacitor and a small inductor. 10-lead, 3mm x 3mm QFN Package and 8- Fault protection includes hiccup short-circuit lead SOICE package protection, cycle-by-cycle current limiting and thermal shutdown. Other features include APPLICATIONS frequency synchronization input and internal P/ASIC/DSP/FPGA Core and I/O Supplies soft-start. Printers and LCD TVs The MP2212 is available in small 3mm x 3mm Network and Telecom Equipment 10-lead QFN and 8-lead SOIC with exposed Point of Load Regulators pad packages. All MPS parts are lead-free and adhere to the RoHS directive. For MPS green status, please visit MPS website under Quality Assurance.
