Beschreibung

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.

Eigenschaften
