The Texas Instruments LM5163HQDDARQ1 is a synchronous buck DC/DC converter designed for automotive applications. It features a wide input voltage range from 6V to 100V and can deliver an output current of up to 0.5A. This device is AEC-Q100 qualified and operates across a junction temperature range of -40°C to 165°C, making it suitable for rugged environments.
The converter utilizes a Constant on-time (COT) control mode and includes an integrated 0.725-Ω NFET buck switch and a 0.34-Ω NFET synchronous rectifier, eliminating the need for an external Schottky diode. It offers features such as Enable, Light Load Efficiency, Over Current Protection, Power good, and Soft Start. The device is optimized for ultra-low EMI requirements, meeting the CISPR 25 class 5 standard.
Packaged in an 8-SO PowerPad (8-PowerSOIC) surface-mount package, the LM5163HQDDARQ1 is designed for integration into scalable automotive power supplies. Its ultra-low quiescent current of 10.5-µA at no load and 3-µA in shutdown contributes to power efficiency. The adjustable switching frequency can be set up to 1 MHz, with low minimum on- and off-times of 50 ns.
