LMR38020FDDAR Description

Short technical summary and product information.

The LMR38020FDDAR from Texas Instruments is a 2A synchronous buck converter belonging to the SIMPLE SWITCHER® power converter family. It operates with an input voltage range of 4.2V to 80V and provides an adjustable output voltage.

 

Key electrical specifications include a maximum output current of 2A, a switching frequency adjustable from 200kHz to 2.2MHz, and an ultra-low quiescent current of 40µA. The device features include Enable, Forced PWM, Frequency synchronization, Light Load Efficiency, Over Current Protection, Power good, Pre-Bias Start-Up, Soft Start, Spread Spectrum, Synchronous Rectification, and UVLO.

 

This converter is housed in an 8-pin SO PowerPad package, suitable for surface mounting. Its operating temperature range is -40°C to 150°C (TJ). The device is functional safety-capable and configured for rugged industrial applications, making it suitable for sectors like Robotics and Test & Measurement.

 

With its integrated compensation network, the LMR38020FDDAR simplifies design and reduces Bill of Materials (BOM) count. The spread spectrum option helps in reducing electromagnetic interference (EMI).
