CX8509 Datasheet (Core Micro Technology) - Monolithic Synchronous Buck Regulator

CX8509, Monolithic Synchronous Buck Regulator

The CX8509 is a monolithic synchronous buck regulator.

The device integrates 100mΩ MOSFETS that provide 2A continuous load current over a wide operating input voltage of 4.75V to 25V.

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

An adjustable soft-start pre
