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.
