LMR33630BRNXR Description

Short technical summary and product information.

The LMR33630BRNXR from Texas Instruments is a 3A synchronous step-down (buck) DC-DC converter. It is part of the SIMPLE SWITCHER® family, designed for ease of use and high performance in industrial applications.

 

This converter operates with an input voltage range of 3.8V to 36V and can provide an adjustable output voltage from 1V to 24V, with a maximum output current of 3A. It features a switching frequency of 1.4MHz, contributing to its compact solution size and high efficiency, with peak efficiency exceeding 95%. The device includes integrated power MOSFETs with low RDS-ON (75mΩ/50mΩ) and supports features like Enable, Light Load Efficiency, Over Current Protection, Power Good, and Pre-Bias Start-Up.

 

The LMR33630BRNXR is housed in a 12-VQFN-HR (3x2 mm) package with wettable flanks for improved solder joint inspection. Its operating temperature range is -40°C to 125°C (TJ). The converter utilizes peak-current-mode control and offers low EMI and low switching noise, making it suitable for applications requiring clean power delivery. Documentation is available to aid in functional safety system design, and the device is rated as Functional Safety-Capable.
