MIC28304 - 70V 3A Power Module

General Description

Micrel’s MIC28304 is synchronous step-down regulator module, featuring a unique adaptive ON-time control architecture.

The module incorporates a DC-to-DC controller, power MOSFETs, bootstrap diode, bootstrap capacitor and an inductor in a single package.

Key Features

  • These include undervoltage lockout, internal soft-start, foldback current limit, “hiccup” mode short-circuit protection, and thermal shutdown. Datasheets and support documentation are available on Micrel’s web site at: www. micrel. com. Features.
  • Easy to use.
  • Stable with low-ESR ceramic output capacitor.
  • No compensation and no inductor to choose.
  • 4.5V to 70V input voltage.
  • Single-supply operation.
  • Power Good (PG) output.
  • Low radiated.
