FEATURES
3A Output Current Wide 4.5V to 27V Operating Input Range Integrated 100mΩ Power MOSFET Switches Output Adjustable from 0.925V to 24V Up to 96% Efficiency Programmable Soft-Start Stable with Low ESR Ceramic Output Capacitors Fixed 400KHz Frequency Cycle-by-Cycle Over Current Protection Input Under Voltage Lockout SOP8L-EP Package TYPICAL APPLICATION Distributed Power Systems Networking Systems FPGA, DSP, ASIC Power Supplies Green Electronics/ Appliances Notebook Computers GENERAL DESCRIPTION
Current mode control provides fast transient response and cycle-by-cycle cur-rent limit. An adjustable soft-start prevents inrush current at turn on. In shutdown mode, the supply cur-rent drops below 1µA. This device, available in an SOP8L-EP package, provides a very compact system solution with minimal reliance on external components.
