Overview
The SC2672STRT is a dual synchronous buck switching controller manufactured by Semtech. It operates as a voltage mode PWM controller with two independent outputs. The device supports a switching frequency of 300 kHz and delivers an output current of 12 A per channel. It features a maximum duty cycle of 95% and regulates outputs down to 2.75 V. The controller functions within a supply voltage range of 3 V to 15 V, drawing 10 mA of operating current. It is housed in a 16-pin SOIC package and operates between -40°C and +85°C.
Feature Summary
- Dual synchronous buck topology for independent or combined power delivery
- Voltage mode PWM control with internal high-side drive circuitry
- 180-degree phase shifting between channels to minimize input and output ripple
- Integrated soft start functionality
Applications
- Point-of-load regulation for systems requiring multiple distinct voltage rails
- Power distribution units utilizing flexible input configurations such as 3.3V, 5V, or 12V
- Industrial equipment requiring isolated or non-isolated dual-channel power management
Procurement Notes
Verify the specific suffix STRT indicates reel packaging when ordering. Confirm the active status and RoHS compliance details directly with Semtech or authorized distributors prior to procurement. Ensure the SOIC-16 footprint matches the target PCB design. Check for any lead-free or environmental declarations required by the end application standards.
Selection Notes
Select this component when dual independent synchronous buck conversion is required from a single IC. It is suitable for applications needing 300 kHz operation and 12 A output capability per channel. Consider the 16-pin SOIC package constraints and the 3 V to 15 V input voltage range. Verify that the 2.75 V minimum output voltage meets the load requirements.
Part Context
The SC2672 belongs to the SC26 series of power management integrated circuits from Semtech. This series focuses on dual synchronous voltage mode controllers designed for efficient power conversion. The part integrates necessary drive circuitry and protection features into a compact surface-mount package for industrial and commercial power supplies.
Replacement Considerations
Consult official Semtech documentation for verified cross-references. No public substitute part numbers are confirmed in the provided source material.
