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.

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.

Features
• Supports Power- and Sequencing requirements of modern Processors
• Supports Cranking Profiles
• Supports Peripheral Supplies (I/Os, Memory)
• Small form factor
• Cost-effective

Parts Include:

TPS22965-Q1 5.5V, 4A, 16mΩ Automotive Load Switch With Adjustable Rise Time and Optional Quick Output Discharge
