A8590 - 3.0A Asynchronous Buck Regulator

General Description

Designed to provide the power supply requirements of nextgeneration car audio and infotainment systems, the A8590 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.
  • Uses pulse frequency modulation (PFM) to draw only tens of microamperes from VIN while maintaining keepalive VOUT.
  • PWM/PFM mode control input pin.
  • Delivers up to 3.0 A of output current with integrated 110 mΩ high voltage MOSFET.
  • SLEEP input pin commands ultra-low current shutdown mode.
  • Adjustable outpu.
