LSP5523
LSP5523 is 3A 27V Synchronous Buck Converter manufactured by Diodes Incorporated.
Description
The DIODES™ LSP5523 is a monolithic synchronous buck regulator. The device integrates 90mΩ 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. An adjustable soft-start prevents inrush current at turn on.
