Quality Control: Learn More
Texas Instruments LM2647LQ is a dual-output, step-down DC-DC controller IC. This buck regulator operates with an input voltage range of 5.5V to 28V and features a switching frequency adjustable between 200kHz and 500kHz. The device offers two positive output configurations, supporting transistor driver output types and two output phases. Key control features include current limit, enable, frequency control, power good indication, and soft start. The LM2647LQ utilizes a buck topology and incorporates synchronous rectification. It is supplied in a 28-WFQFN exposed pad package with dimensions of 5x5mm and is available on tape and reel. This component is suitable for applications in power management systems.
