A8580 - Asynchronous Buck Regulator

General Description

Designed to provide the power supply requirements of next generation car audio and infotainment systems, the A8580 provides all the control and protection circuitry to produce a high current regulator with ±1.0% output voltage accuracy.

Key Features

  • Automotive AEC-Q100 qualified.
  • Withstands surge voltages up to 40 V.
  • Operates as low as 3.4 VIN (typ) with VIN decreasing.
  • Utilizes pulse frequency modulation (PFM) to draw only tens of microamperes from VIN while maintaining keep-alive VOUT.
  • PWM/PFMn mode control input pin.
  • Delivers up to 2.5 A of output current with integrated 110 mΩ high voltage MOSFET.
  • SLEEPn input pin commands ultra-low current shutdown mode.
  • Adjustabl.
