MP2303DN - 340KHz Synchronous Rectified Step-Down Converter

Download the MP2303DN datasheet PDF. This datasheet also covers the MP2303 variant, as both devices belong to the same 340khz synchronous rectified step-down converter family and are provided as variant models within a single manufacturer datasheet.

Description

The MP2303 is a monolithic synchronous buck regulator.

The device integrates power MOSFETS that provide 3A continuous load current over a wide operating input voltage of 4.75V to 28V.

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

Features

  • 3A Output Current.
  • Wide 4.75V to 28V Operating Input Range.
  • Integrated Power MOSFET Switches.
  • Output Adjustable from 0.8V to 25V.
  • 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.
  • Thermally Enhanced 8-Pin SOIC and 3x3 QFN10 Packages.

The Future of Analog IC Technology MP2303 3A, 28V, 340KHz Synchronous Rectified Step-Down Converter DESCRIPTION The MP2303 is a monolithic synchronous buck regulator. The device integrates power MOSFETS that provide 3A continuous load current over a wide operating input voltage of 4.75V to 28V. 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 8-pin SOIC and 3x3 10-pin QFN packages, provides a very compact system solution with minimal reliance on external components. EVALUATION BOARD REFERENCE Board Number EV2303DN-00A Dimensions 2.0”X x 1.5”Y x 0.5”Z FEATURES  3A Output Current  Wide 4.
