GENERAL DESCRIPTION

The MA5805 is a monolithic asynchronous buck regulator. The device integrates 110mΩ

MOSFET, and provides 2A of continuous load current over a wide input voltage of 10V to 58V.

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

The internal soft-start function prevents inrush current at turn-on, This device, available in an

SOP8L-EP(Exposed pad) package, provides a very compact solution with minimal external

components.
