LMQ62440CPPQRJRRQ1 Description

Short technical summary and product information.

The LMQ62440CPPQRJRRQ1 from Texas Instruments is a high-performance synchronous step-down (buck) converter designed for automotive applications. It features a wide input voltage range of 3 V to 36 V and can supply a maximum output current of 4 A. This device is optimized for ultra-low EMI requirements, meeting CISPR25 Class 5 standards, and incorporates features like integrated capacitors and spread spectrum control to minimize noise.

 

The converter operates in current mode with a fixed frequency and includes several key features such as Enable, Forced PWM, Frequency Synchronization, Light Load Efficiency, Over Current Protection, Power Good, and Soft Start. Its Hotrod package minimizes switch node ringing and supports wettable flanks for improved solder joint inspection. The operating temperature range is -40°C to 150°C.

 

Designed for rugged automotive environments, the LMQ62440CPPQRJRRQ1 supports 42-V load dump conditions and offers a typical dropout voltage of 0.4 V at a 4-A load. It achieves high efficiency power conversion across all loads, with a notably low quiescent current of 7 µA at 13.5 V IN and 3.3 V OUT. The device is AEC-Q100 qualified and functional safety-capable, with documentation available to aid functional safety system design.
