The Semtech Corporation SC1103CS-TR is a high-efficiency, voltage-mode, synchronous buck controller IC. This device is designed for step-down DC-DC conversion with a 3.8V to 12V input supply. It features a fixed 200kHz switching frequency, enabling the use of smaller passive components. The SC1103CS-TR supports a maximum duty cycle of 95%, making it suitable for applications requiring high step-down ratios. It operates as a single-output, positive voltage regulator, driving external P-channel and N-channel MOSFETs for a complete power stage. This component is housed in an 8-SOIC package suitable for surface mounting and is supplied on tape and reel. The SC1103CS-TR finds application in power supplies for consumer electronics and industrial control systems.
