Overview
The SC1102CSTRT is a synchronous voltage-mode controller manufactured by Semtech Corporation, designed for single-ended power supply applications where efficiency is critical. It features internal level-shift high-side drive circuitry and preset shoot-through control, enabling the use of inexpensive N-channel power switches. The device includes an on-chip power good function, overvoltage protection (OVP), soft start, and enable functionality. It operates with a 1.265V reference and supports RDS(ON) current sensing to minimize external components.
Feature Summary
- Synchronous operation capability for high efficiency
- Internal level-shift high-side drive circuitry
- Integrated power good and overvoltage protection functions
- Soft start and enable functionality
Applications
- Microprocessor core supply
- Low cost synchronous applications
- Voltage Regulator Modules (VRM)
- DDR termination supplies
- Networking power supplies
Procurement Notes
Verify the specific suffix 'CSTR' against the manufacturer's official documentation to confirm tape and reel packaging specifications. Ensure compatibility with the required 14-pin SOIC lead-free package form factor. Cross-reference the RoHS compliance status directly with the latest datasheet revision to meet environmental regulations. Confirm that the component meets WEEE directives as stated in the product description.
Selection Notes
Select this controller for distributed power applications requiring high efficiency without heat sinks. The internal drive circuitry simplifies design by allowing low-cost N-channel MOSFETs. Consider the small footprint requirement due to minimum external component count. Evaluate the need for sequenced power supplies or specific networking power architectures when choosing this synchronous mode controller.
Part Context
The SC1102 series consists of low-cost, full-featured synchronous voltage-mode controllers. The SC1102CSTRT variant belongs to this family, optimized for single-ended power supplies. It is part of Semtech's portfolio aimed at providing efficient power management solutions for advanced microprocessors and distributed power systems.
Replacement Considerations
Public confirmed substitute part numbers include SC1102ASTR, SC1102ASTRT, and SC1102CS.TR. These variants share the same functional description as synchronous voltage-mode controllers for distributed power supply applications.
