Quality Control: Learn More
Semtech Corporation SC2544MLTRT is a 2-phase, step-down DC-DC controller IC. Featuring a current-mode control architecture, this device supports a wide input voltage range of 4.5V to 28V and a maximum duty cycle of 90%. The switching frequency is adjustable between 100kHz and 300kHz. Control features include current limiting, enable, frequency control, phase control, power good indication, and soft-start functionality. The SC2544MLTRT utilizes a buck topology and is designed for surface mounting in a 24-MLPQ (4x4) package, supplied on tape and reel. Its output stage drives external transistors, and it incorporates synchronous rectification. This component is suitable for applications in industrial, automotive, and consumer electronics requiring efficient power conversion.
