LSP5527 Datasheet | LITEON

Description The LSP5527 is a monolithic synchronous buck regulator. The device integrates 95 mΩ MOSFETS that provide 2A continuous load current over a wide operating input voltage of 4.5V to 27V. Current mode control provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush current at turn on. Features - 2A Output Current - Wide 4.5V to 27V Operating Input Range - Integrated Power MOSFET Switches - Output Adjustable from 0.925V to 0.8Vin - Up to 96% Efficiency - Programmable Soft-Start - Stable with Low ESR Ceramic Output Capacitors - Fixed 340KHZ Frequency - Cycle by Cycle Over Current Protection - Short Circuit Protection - Input Under Voltage Lockout - Package： SOP-8L Applications - Distributed Power Systems - Networking Systems - FPGA, DSP, ASIC Power Supplies - Green Electronics/ Appliances - Notebook puters Please be aware that an Important Notice concerning availability, disclaimers, and use in critical applications of LSC products is at the end of this document.
