SC1175CSWTRT

Overview

The SC1175CSWTRT is a low-power dual synchronous DC/DC controller manufactured by Semtech Corporation. It features two independent channels designed for high-performance voltage mode PWM control, suitable for applications requiring current sharing circuitry. The device operates within a temperature range of 0°C to +70°C and utilizes an SOIC-20 surface-mount package.

Feature Summary

• Dual synchronous buck topology with integrated current sharing circuitry
• Voltage mode PWM control for independent channel operation
• Low power consumption design optimized for efficiency

Applications

• Audio power supplies
• General-purpose power supply systems
• Industrial equipment requiring dual rail regulation

Procurement Notes

Verify the specific suffix 'TRT' indicates tape and reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SOIC-20 footprint matches the target PCB layout requirements for proper assembly.

Selection Notes

Select this component for designs requiring two isolated or non-isolated synchronous buck outputs controlled by a single IC. It is appropriate for systems needing precise current sharing between channels without external complex logic. Consider thermal management capabilities within the specified operating temperature range during board design.

Part Context

This part belongs to the SC117 series of switching controllers from Semtech. It complements other voltage mode PWM controllers in the portfolio, offering a specialized solution for dual-channel applications where space and power efficiency are critical constraints in compact electronic designs.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic equivalents may lack the specific current sharing architecture. Verify pin compatibility and electrical specifications before substitution.
