LSP5522L Datasheet | LITEON

2A 18V Synchronous Buck Converter 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 The LSP5522L is a monolithic synchronous buck regulator. The device integrates 150mΩ MOSFETS that provide 2A continuous load current over a wide operating input voltage of 4.5V to 18V. 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 puters Typical Application Circuit V IN = 12V R4 100K C1 22uF BS VIN...
