MP2403DN - 250kHz Integrated Synchronous Step-Down Converter

Download the MP2403DN datasheet PDF. This datasheet also covers the MP2403 variant, as both devices belong to the same 250khz integrated synchronous step-down converter family and are provided as variant models within a single manufacturer datasheet.

General Description

The MP2403 is a monolithic synchronous buck regulator.

The device integrates a 150mΩ high-side MOSFET and an 80mΩ low-side MOSFET that provides 3A continuous load current over a wide operating input voltage of 4.6V to 32V.

Key Features

  • 3A Output Current.
  • Wide 4.6V to 32V Operating Input Range.
  • Integrated MOSFET Switches.
  • Output Adjustable from 0.80V to 28V.
  • Up to 95% Efficiency.
  • Programmable Soft-Start.
  • Stable with Low ESR Ceramic Output Capacitors.
  • Fixed 250kHz Frequency.

The Future of Analog IC Technology MP2403 3A, 32V, 250kHz Integrated Synchronous Step-Down Converter DESCRIPTION The MP2403 is a monolithic synchronous buck regulator. The device integrates a 150mΩ high-side MOSFET and an 80mΩ low-side MOSFET that provides 3A continuous load current over a wide operating input voltage of 4.6V to 32V. Current mode control provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush current at turn-on. In shutdown mode, the supply current drops to 1μA. This device, available in an 8-pin SOIC package, provides a very compact system solution with minimal reliance on external components.
