TM MP1591 2A, 32V, 330KHz Step-Down Converter The Future of Analog IC Technology TM DESCRIPTION The MP1591 is a high voltage step-down converter ideal for automotive power adapter battery chargers. Its wide 6.5V to 32V input voltage range covers the automotive battery’s requirements and it achieves 2A continuous output for quick charge capability. Current mode operation provides fast transient response and eases loop stabilization. Fault protection includes cycle-by-cycle current limiting and thermal shutdown. In shutdown mode, the converter draws only 20A of supply current. The MP1591 requires a minimum number of readily available external components to complete a 2A step-down DC to DC converter solution. FEATURES Wide 6.5V to 32V Input Operating Range 34V Absolute Maximum Input 2A Output Current 120m Internal Power MOSFET Switch Stable with Low ESR Output Ceramic Capacitors Up to 95% Efficiency 20A Shutdown Mode Fixed 330KHz Frequency Thermal Shutdown Cycle-by-Cycle Over Current Protection Output Adjustable From 1.23V to 21V Under Voltage Lockout Reference Voltage Output Available in 8-Pin SOIC Packages Automotive Power Adapters PDA and Cellular Phone Battery Chargers Distributed Power Systems Automotive Aftermarket Electronics APPLICATIONS EVALUATION BOARD REFERENCE Board Number EV0020 Dimensions 2.1”X x 1.4”Y x 0.5”Z “MPS” and “The Future of Analog IC Technology” are Trademarks of Monolithic Power Systems, Inc.
