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 40V
- Dual high-current synchronous outputs: 5V, up to 10A; 3.3V, up to 10A
- Continuous operation during engine crank transient down to 2.5V
- Reverse battery protection with zero IQ smart diode controller
- Minimized AM radio band interference
