SD46520 - 400KHZ 2A STEP-DOWN DC-DC CONVERTER

Description

The SD46520 is a step-down PWM control converter with a built-in internal power MOSFET.

It achieves 2A continuous output current over a wide input supply range with excellent load and line regulation.

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

Features

  • 2A output current.
  • 0.2Ω internal power MOSFET.
  • Stable with low ESR output ceramic capacitor.
  • Up to 95% conversion efficiency.
  • shutdown mode.
  • 400kHz fixed frequency.
  • Thermal shutdown.
  • Cycle-by-cycle over current protection.
  • 4.75－18V input voltage range.
  • 1.22－16V output voltage range.
  • Programmable under voltage control.
