LSP5526 2A 23V Synchronous Buck Converter

General Description

The LSP5526 is a monolithic synchronous buck regulator. The device integrates 95mΩ MOSFETS that

provide 2A 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.
