LMR33630CDDA Description

Short technical summary and product information.

The LMR33630CDDA from Texas Instruments is a 3A synchronous step-down (buck) voltage converter. It is part of the SIMPLE SWITCHER® family, designed for rugged industrial applications with an input voltage range of 3.8V to 36V.

 

This converter features an adjustable output voltage ranging from 1V to 34V and can deliver up to 3A of current. Key electrical specifications include a switching frequency of up to 2.1 MHz, a peak efficiency greater than 95%, and a low quiescent current of 25 µA. It utilizes peak-current-mode control and has a short minimum on-time of 68 ns.

 

The LMR33630CDDA is available in an 8-SO PowerPad package, suitable for surface mounting. It offers features such as Enable, Light Load Efficiency, Over Current Protection, Power Good, Pre-Bias Start-Up, and Synchronous Rectification. The device also boasts low EMI and low switching noise, with an integrated compensation network.

 

This component is Functional Safety-Capable, with documentation available to aid functional safety system design. Its design considerations include parallel input current paths and wettable flanks packaging for improved assembly inspection.
