LMR34206SC3QRNXTQ1 Description

Short technical summary and product information.

The LMR34206SC3QRNXTQ1 from Texas Instruments is an easy-to-use, synchronous, step-down DC/DC converter designed for automotive applications. It integrates high-side and low-side power MOSFETs, delivering up to 0.6A of output current over a wide input voltage range of 4.2V to 42V.

 

This device utilizes peak-current-mode control for optimal efficiency and output voltage accuracy. It features a 2.1MHz switching frequency, enabling the use of small external components and reducing solution size. The regulator offers protection features such as thermal shutdown, input undervoltage lockout, and cycle-by-cycle current limit.

 

The LMR34206SC3QRNXTQ1 is housed in a small 2mm x 3mm VQFN package with wettable flanks, suitable for surface mounting. Its design optimizes for ultra-low EMI requirements, meeting CISPR25 class 5 standards. The device is AEC-Q100 qualified for automotive applications, with an operating temperature grade of 1 (–40°C to +125°C).

 

Key features include a low operating quiescent current of 24 µA, a typical dropout voltage of 0.2V at 0.6A load, and ±1.5% reference voltage tolerance. It offers fixed output voltage options, including 3.3V and 5V, and is pin-compatible with other LMR-Q1 series converters for scalable power supply designs.
