A8586-1 - 3.5 Amp Buck Regulator

Download the A8586-1 datasheet PDF. This datasheet also covers the A8586 variant, as both devices belong to the same 3.5 amp buck regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The A8586 is a high frequency step-down switching regulator with an integrated high-side power MOSFET.

It provides up 3.5 A output current.

The A8586 can achieve fast transient response using current-mode control and simple external compensation.

Key Features

  • Automotive AEC-Q100 qualified.
  • Supply voltage from 3.8 to 36 V.
  • Output voltage adjustable from 0.8 to 30 V.
  • Maximized duty cycle for low dropout operation.
  • Low 30 μA operational quiescent current.
  • 150 mΩ integrated MOSFET switch.
  • Programmable switching frequency up to 4 MHz.
  • Improved EMC with frequency dithering (A8586 and A8586-2) and controlled switch node rise and fall times.
  • Ceramic capacitor stable.
  • I.
