MP2305SDS - 23V Synchronous Rectified Step-Down Converter

Download the MP2305SDS datasheet PDF. This datasheet also covers the MP2305S variant, as both devices belong to the same 23v synchronous rectified step-down converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The MP2305S is a monolithic synchronous buck regulator.

The device integrates a 175mΩ high-side MOSFET and a 115mΩ low-side MOSFET that provide 2A continuous load current over a wide operating input voltage of 4.75V to 23V.

Key Features

  • 2A Output Current.
  • Wide 4.75V to 23V Operating Input Range.
  • Integrated Power MOSFET Switches.
  • Output Adjustable from 0.923V to 20V.
  • Up to 95% Efficiency.
  • Programmable Soft-Start.
  • Stable with Low ESR Ceramic Output Capacitors.
  • Fixed 340KHz Frequency.
  • Cycle-by-Cycle Over Current Protection.
  • Input Under Voltage Lockout.

MP2305S 2A, 23V Synchronous Rectified Step-Down Converter NOT RECOMMENDED FOR NEW DESIGNS, REFER TO MP2331 DESCRIPTION The MP2305S is a monolithic synchronous buck regulator. The device integrates a 175mΩ high-side MOSFET and a 115mΩ low-side MOSFET that provide 2A continuous load current over a wide operating input voltage of 4.75V to 23V. Current mode control provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush current at turn-on. Shutdown mode drops the supply current to 1μA. This device, available in an 8-pin SOIC package, provides a very compact system solution with minimal reliance on external components.
