A4412 - Buck or Buck/Boost Pre-Regulator

General Description

The A4412 is a power management IC that uses a buck or buck/ boost pre-regulator to efficiently convert automotive battery voltages into a tightly regulated intermediate voltage complete with control, diagnostics and protections.

Key Features

  • A2-SIL™ product.
  • device features for safety critical systems.
  • Automotive AEC-Q100 qualified.
  • Wide input voltage range, 3.8 to 40 VIN operating range, 50 VIN maximum.
  • Buck or buck/boost pre-regulator (VREG).
  • Adjustable 1.3 to 3.3 V, 400 mA synchronous buck.
  • Four internal linear regulators with foldback short-circuit protection, 3.3 V (3V3) and three 5 V (V5CAN, V5A, and V5B).
  • One internal 5 V linear regulator (V5P) with foldb.
