LMR33640DDDAR Description

Short technical summary and product information.

The LMR33640DDDAR from Texas Instruments is a 4A synchronous step-down converter designed for rugged industrial applications. It features a wide input voltage range from 3.8V to 36V and an adjustable output voltage range of 1V to 24V.

 

This converter utilizes peak-current mode control and operates at a switching frequency of 1MHz. It offers high efficiency, with peak efficiency exceeding 95%, and low quiescent currents of 24µA during operation and 5µA in shutdown mode. The device includes features such as Enable, Light Load Efficiency, Over Current Protection, Power Good, Pre-Bias Start-Up, and Synchronous Rectification.

 

Packaged in an 8-pin SOIC package with wettable flanks, the LMR33640DDDAR is suitable for surface mount applications. Its pin compatibility with other LMR336xx and LMR365xx series devices allows for scalable power supply designs. The integrated compensation simplifies design complexity and reduces solution size and cost.
