Description

  • TIDA-00801.3, Automotive Off-Battery Infotainment Processor Power Reference Design. The TIDA-00801 reference design is a full off-battery to point of load power solution supporting input voltages as low as 2V. It uses the Boost plus Buck DC/DC regulator TPS43330A-Q1 supporting an input voltage range of 2V to 40V and allowing the design to support not only start-stop but also cold crank conditions. The TPS659039-Q1 integrated power management IC supplies point of load power to an application processor such as the TDA2x/DRA7xx. Also included is a 5V/4A load switch, the TPS22965-Q1 and a linear regulator TPS51200-Q1 for DDR termination supply
