AEC-Q100, 55V Synchronous Boost Controllers-Image

Highly Integrated 55V Sync Boost Controllers Enable Smaller, More Robust Designs

Intersil’s ISL78227/29 2-phase synchronous boost controllers help simplify the design of your high voltage automotive applications. Operating from a 12V battery supply, the AEC-Q100 qualified controllers efficiently boost the output voltage to 24V, 36V or 48V.

The robust ISL78227/29 devices offer >95% efficiency and multiple protection features to enable operation under virtually any condition.

Key Features

  • Provides input/output voltage from 5V to 55V, and withstands transients up to 60V
  • Supports synchronous or standard boost topology, and uses peak current mode control for fast line response with adjustable slope compensation
  • Configurable for single phase, 2-phase and 4-phase operation, enabling high efficiency
  • Adjustable switching frequency from 50kHz to 1.1MHz, and external synchronization
  • Two layers of over-current protection prevents inductor current run-away system damage
  • Integrated high-side and low-side MOSFET drivers
