The LMR34206FSC5RNXRQ1 from Texas Instruments is an ultra-small, synchronous step-down DC/DC converter designed for automotive applications. It accepts an input voltage range from 4.2V to 42V and delivers a fixed output voltage of 3.3V with a maximum output current of 0.6A.
This converter operates at a switching frequency of 2.1MHz, enabling the use of smaller inductors. Key electrical features include a typical quiescent current of 25 nA, a maximum duty cycle of 99%, and a typical dropout voltage of 0.2V at 0.6A load. It also offers a reference voltage tolerance of ±1.5%.
The device is housed in a 12-VQFN-HR (3x2 mm) package with wettable flanks, suitable for surface mounting. The operating temperature range is -40°C to 125°C (TJ), and it is AEC-Q100 qualified for automotive applications. Protection features include thermal shutdown, input undervoltage lockout, and cycle-by-cycle current limit with hiccup short-circuit protection.
Features such as Enable, Fixed Output, Fixed soft start, Light-load efficiency, Power good, Spread Spectrum, and Synchronous Rectification are integrated. The device is also Functional Safety-Capable.
