4A 32V 320kHz Synchronous Rectified Step - Down CX8518
DESCRIPTION
The CX8518 is a monolithic synchronous buck regulator. The device integrates 100m? MOSFETS that provide 4A of continuous load current over a wide operating input voltage of 4.75V to 32V. Current mode cool provides fast transient response and cycle-by-cycle current limit.An adjustable soft-start prevents inrush current at turn on and in shutdown mode, the supply current drops below 1?A.
FEATURES
? 4A Continuous Output Current
? Wide 4.75V to 32V Operating Input Range
? Integrated 100m? Power MOSFET Switches
? Output Adjustable from 0.925V to 20V
? Up to 93% Efficiency
? Programmable Soft-Start
? Stable with Low ESR Ceramic Output Capacitors
? Fixed 320KHz Frequency
? Cycle-by-Cycle Over Current Protection
? Input Under Voltage Lockout
? Thermally Enhanced 8-Pin SOIC Package
APPLICATIONS
? Distributed Power Systems
? Networking Systems
? FPGA, DSP, ASIC Power Supplies
? Green Electronics/Appliances
? Notebook Computers
