Automotive Off-battery VCM Supporting 2.5-V Cold Crank Profile Reference Design
Description
This reference design is a high-current: wide input voltage range circuit that can handle engine cold crank profile down to 2.5V. The dual-output voltages are 5V and 3.3V that support up to 10A for each output. The design is suitable for an automotive off-battery infotainment application that needs to support a very stringent starting profile down to 2.5V.
Features
- Wide input voltage range of 2.5V to 40VDual high-current synchronous outputs: 5V: up to 10A; 3.3V: up to 10AContinuous operation during engine crank transient down to 2.5VReverse battery protection with zero IQ smart diode controllerMinimized AM radio band interference
