MP2459GJ - Step-Down Converter

Download the MP2459GJ datasheet PDF. This datasheet also covers the MP2459 variant, as both devices belong to the same step-down converter family and are provided as variant models within a single manufacturer datasheet.

Description

The MP2459 is a monolithic, step-down, switchmode converter with a built-in power MOSFET.

It achieves a 0.5A peak-output current over a wide input supply range with excellent load and line regulation.

Current-mode operation provides a fast transient response and eases loop stabilization.

Features

  • 0.5A Peak Output Current.
  • 1Ω Internal Power MOSFET.
  • Stable with Low-ESR Ceramic Output Capacitors.
  • Up to 90% Efficiency.
  • 0.1μA Shutdown Mode.
  • Fixed 480kHz Frequency.
  • Thermal Shutdown.
  • Cycle-by-Cycle Over-Current Protection.
  • Wide 4.5V-to-55V Operating Input Range.
  • Output Adjustable from 0.81V to 0.95.
  • VIN.
  • Available in a TSOT23-6 Package.
