Description

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.Benefits:Supports cold and warm cranking: supports modern processors sequencing needs without further logic: supports peripherals and is a small form-factor:  low system-cost solution.
