LSP5527

Description

The LSP5527 is a monolithic synchronous buck regulator. The device integrates 95 mΩ MOSFETS that
provide 2A continuous load current over a wide operating input voltage of 4.5V to 27V. Current mode control
provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush
current at turn on.
