LM5164DDAR Description

Short technical summary and product information.

The Texas Instruments LM5164DDAR is a highly integrated, synchronous buck DC-DC converter designed for reliable and rugged applications. It operates over a wide input voltage range of 6V to 100V, making it suitable for various power management needs.

Key electrical specifications include a maximum output current of 1A and an adjustable output voltage ranging from 1.2V to 90V. The converter boasts an ultra-low quiescent current of 10.5µA in no-load conditions and 3µA in shutdown mode. It features a constant on-time (COT) control mode, adjustable switching frequency up to 1MHz, and integrated 0.725Ω NFET buck switch and 0.34Ω NFET synchronous rectifier.

Designed for scalability, the LM5164DDAR is optimized for ultra-low EMI requirements, meeting CISPR 25 class 5 standards. It includes features such as Enable, Light Load Efficiency, Over Current Protection, Power Good indication, Pre-Bias Start-Up, Synchronous Rectification, and adjustable UVLO. The device also incorporates peak and valley current-limit protection, input UVLO, and thermal shutdown protection.

Packaged in an 8-SO PowerPad (8-PowerSOIC) surface mount package, the LM5164DDAR operates within a junction temperature range of -40°C to +150°C. Its integration reduces design size and cost, making it ideal for industrial power supplies and battery packs.
