LSP5503 Datasheet (Liteon Semiconductor) - 3A Synchronous Step Down DC/DC Converter

LSP5503, 3A Synchronous Step Down DC/DC Converter

The LSP5503 is a monolithic synchronous buck regulator.

The device integrates 100mΩ MOSFETS that provide 3A continuous load cur-rent over a wide operating input voltage of 4.5V to 27V.

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

An adjustable soft-start p
