MA5805 - 58V Asynchronous Buck Converter

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.

Key Features

  • - Wide 10V to 58V Operating Input Range - 3.3V / 5V Output Voltage (for POE) - Integrated 110mΩ P-channel MOSFET Switches - Output Adjustable :VFB(1.00V±2%) - Internal Soft-Start - Fixed 500KHz Frequency - Cycle-by-Cycle Over Current Protection - Input Under/Over Voltage Lockout .

MA5805 58V Asynchronous Buck Converter for POE  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.  FEATURES - Wide 10V to 58V Operating Input Range - 3.3V / 5V Output Voltage (for POE) - Integrated 110mΩ P-channel MOSFET Switches - Output Adjustable :VFB(1.
