FEATURES
2A Output Current Wide 4.5V to 18V Operating Input Range Integrated Power MOSFET Switches Output Adjustable from 0.925V to 12V Up to 96% Efficiency Programmable Soft-Start Stable with Low ESR Ceramic Output Capacitors Fixed 360KHZ Frequency Cycle-by-Cycle Over Current Protection Input Under Voltage Lockout Package SOP-8L APPLICATIONS
Distributed Power Systems Networking Systems FPGA, DSP, ASIC Power Supplies GENERAL DESCRIPTION
Current mode control provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush current at turn on. In shutdown mode, the supply current drops below 1uA. Green Electronics/ Appliances Notebook Computers Typical Application Circuit V IN = 12V R4 100K C1 22uF BS VIN SW LSP5522
