LSP5503
3A Synchronous Step Down DC/DC Converter
FEATURES GENERAL DESCRIPTION
3A Output Current The LSP5503 is a monolithic synchronous buck
Wide 4.5V to 27V Operating Input Range regulator. The device integrates 100m MOSFETS
Integrated 100m Power MOSFET Switches that provide 3A continuous load cur-rent over a wide
Output Adjustable from 0.925V to 24V operating input voltage of 4.5V to 27V. Current mode
Up to 96% Efficiency control provides fast transient response and
Programmable Soft-Start cycle-by-cycle cur-rent limit.
Stable with Low ESR Ceramic Output Capacitors An adjustable soft-start prevents inrush current at turn
Fixed 400KHz Frequency on. In shutdown mode, the supply cur-rent drops
Cycle-by-Cycle Over Current Protection below 1
