A8582 - 2.0A Asynchronous Buck Regulator

General Description

The A8582 is an adjustable frequency, high output current, PWM regulator that integrates a low resistance, high-side, N-channel MOSFET.

The A8582 incorporates current-mode control to provide simple compensation, excellent loop stability, and fast transient response.

Key Features

  • Automotive AEC-Q100 qualified.
  • Wide operating voltage range: 4.7 to 36 V.
  • UVLO stop threshold is at 3.8 V (typ).
  • Supports 40 V input for surge and load dump testing.
  • Capable of at least 2.0 A steady-state output current.
  • Adjustable output voltage as low as 0.8 V.
  • Internal 70 mΩ high-side switching MOSFET.
  • Adjustable switching frequency, fSW: 0.25 to 2.4 MHz.
  • Synchronization to external clock: 1.2 × fSW to 1.5 × fSW.
