A4410 - Adjustable Frequency Buck or Buck/Boost Pre-Regulator

Description

The A4410 is 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.

Features

  • Automotive AEC-Q100 qualified.
  • 2.8 VIN to 36 VIN operating range, 40 VIN maximum.
  • Buck or buck/boost pre-regulator (VREG).
  • Adjustable PWM switching frequency: 250 kHz.
  • 2.4 MHz.
  • PWM frequency can be synchronized to external clock.
  • 1.25 V/750 mADC/1 APEAK synchronous buck (1V25).
  • 3.3 V (3V3) and 5 V (V5) internal LDO regulators with fold back short circuit protections.
  • 5 V (V5P) internal tracking LDO regulator with f.
