SC1103CS.TR

Overview

The SC1103CS.TR is an asynchronous voltage-mode PWM controller manufactured by Semtech Corporation. Designed for single-ended DC/DC power supply applications, it operates with a 12V input. The device features a fixed-voltage architecture to simplify design implementation. It is packaged in an 8-pin SOIC format and is classified as an obsolete component within the manufacturer's current portfolio.

Feature Summary

Voltage-mode pulse width modulation control
Asynchronous switching topology
Fixed-voltage operation for simplified design

Applications

Single-ended DC/DC power supplies
12V input regulated power conversion systems

Procurement Notes

Verify component authenticity carefully as this part is listed as obsolete. Confirm package integrity and pin configuration against original datasheets before integration. Check for cross-reference availability from authorized distributors or secondary markets due to discontinuation status.

Selection Notes

Select this controller for legacy designs requiring a low-cost voltage-mode solution for 12V inputs. Consider modern alternatives if new development is required due to obsolete status. Ensure thermal management aligns with the SOIC package capabilities for the intended load conditions.

Part Context

This component belongs to Semtech's power management integrated circuit family. It serves as a basic regulator controller for non-synchronous buck converter topologies. The product line focuses on cost-effective solutions for standard industrial and consumer power applications.

Replacement Considerations

Check Semtech documentation for direct pin-compatible successors. Evaluate generic voltage-mode PWM controllers with similar 12V input ratings and SOIC-8 packaging for functional equivalence in retrofit scenarios.
