LSP5526

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
