Intermediate Rail 2MHz Switching Power Supply Withstands Entire Automotive Input Voltage Range

Application circuit illustrates an intermediate 8V switching power supply for an automotive radio and infotainment system. The design withstands the complete automotive input voltage range (including cold crank and load dump conditions), assuring a stable 8V supply for common subsystems such as a CD driver, LCDs, and a radio module in modern infotainment systems
