LSP5523 - 3A 27V Synchronous Buck Converter

Download the LSP5523 datasheet PDF. This datasheet also covers the LSP5523-Lite variant, as both devices belong to the same 3a 27v synchronous buck converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The LSP5523 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 27V.

Current mode control provides fast transient response and cycle-by-cycle current limit.
