- Part of the LSP5503L-LITE comparator family.
3A 23V Synchronous Buck Converter
General Description
The LSP5503L is a monolithic synchronous buck regulator. The device integrates 90 mΩ MOSFETS that provide 3A continuous load current over a wide operating input voltage of 4.5V to 23V. Current mode control provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush current at turn on.
