Wide input voltage range (1.5V to 42V): This means it can maintain stable operation under common voltage fluctuations in automotive power systems, such as cold starts or sudden load drops.

Low static current (off-current IQ ≤ 5µA, standby current IQ ≤ 15µA): This is critical for reducing battery power consumption after the vehicle is turned off, helping to extend battery life.

Programmable output: Four fixed output voltage options (6.8V, 7.5V, 8.5V, or 10.5V) and two configuration modes (start-stop or emergency call) can be set using a single resistor.

Adjustable switching frequency (220kHz to 2.3MHz): A higher switching frequency (≥2.2MHz) helps reduce interference with the AM frequency band and allows the use of smaller external components, saving PCB space.

Comprehensive protection features: Includes adjustable cycle-by-cycle current limiting and thermal shutdown protection, enhancing system reliability and safety.

Compliant with AEC-Q100 standards: Certified through stress testing established by the Automotive Electronics Council, meeting the automotive industry's stringent quality requirements for components.

The LM5150QURUMRQ1 is ideal for the following automotive electronic applications:

Automotive start-stop systems: Ensures stable supply voltage during engine automatic start-stop operations, preventing system reset or malfunction.

Automotive emergency call systems (eCall): Provides stable power from a backup battery even if the main battery supply is interrupted, ensuring the emergency call system functions normally during accidents.

Battery-powered boost converters: Suitable for other applications requiring a wide input voltage range and high-efficiency boost solutions.
