The Texas Instruments LM5164QDDATQ1 is an automotive-qualified synchronous buck DC-DC converter designed for reliable and rugged applications. It operates with an input voltage range of 6V to 100V and can provide an output current of up to 1A.
This converter utilizes Constant on-time (COT) control mode and features integrated synchronous rectification, eliminating the need for an external Schottky diode. Key electrical specifications include an adjustable output voltage from 1.2V to 90V, a switching frequency up to 1MHz, and ultra-low quiescent current of 10.5µA in no-load conditions and 3µA in shutdown.
The LM5164QDDATQ1 is housed in an 8-SO PowerPad package, suitable for surface mounting. It operates within a junction temperature range of -40°C to 150°C and an ambient temperature range of -40°C to 125°C. Features such as over-current protection, power good signal, pre-bias start-up, and soft start enhance its usability in various power supply designs.
Optimized for ultra-low EMI requirements, this device is designed for scalable automotive power supplies. Its integration reduces design size and cost, making it a versatile component for demanding applications.
