Overview
LSP5522L 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.
