SC1110CSTRT

Overview

The SC1110CSTRT is a synchronous buck switching regulator controller manufactured by Semtech Corporation. It operates within a supply voltage range of 4.4V to 12.6V and supports a fixed switching frequency of 250kHz with a maximum duty cycle of 95%. The device features integrated current limit, enable, phase control, and soft start capabilities. It is housed in a 14-SOIC surface-mount package and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrated synchronous rectification for improved efficiency
• Phase control capability for multi-phase configurations
• Built-in soft start function to manage inrush current

Applications

• Point-of-load power regulation
• Industrial equipment power supplies
• Telecommunications infrastructure

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm package integrity and pin alignment prior to assembly. Review manufacturer documentation for handling precautions and storage conditions specific to this discontinued part number.

Selection Notes

Evaluate thermal performance requirements against the specified operating temperature range. Ensure input voltage levels remain within the 4.4V to 12.6V specification. Consider alternative components if long-term supply continuity is critical for the design lifecycle.

Part Context

This component belongs to the Semtech DC-DC switch controller family. It serves as a step-down voltage regulator controller designed for efficient power conversion applications requiring precise control and protection features.

Replacement Considerations

SC1110TSTRT is a documented substitute variant featuring a 14-TSSOP package instead of SOIC.
