ABSTRACT
The article discusses considerations for automotive navigation-system power engineering. Many mid- to high-end automobiles produced today come with a DVD-based GPS navigation system as standard equipment. However, designing a power supply to handle all the different voltage rails within such as system can prove to be as complex as designing the power supply system for a notebook PC. Taking into account constraints for a switching regulator to be considered in an automotive navigation system, it would need the following features and characteristics: a wide input operating range; good efficiency across a wide load range; low quiescent current during normal operation, standby, and shutdown; low thermal resistance; and, minimal noise and electromagnetic interference emissions.
