Overview
The SC2608ASTRT is a synchronous voltage mode PWM controller manufactured by Semtech Corporation, designed for step-down (buck) DC/DC converter applications. It operates with a fixed switching frequency of 250kHz and supports an input supply voltage range of 4.5V to 14V. The device features a maximum duty cycle of 85% and includes integrated control characteristics such as enable, phase control, and soft start functionality. Packaged in an 8-SOIC surface-mount case, it is rated for operation within a junction temperature range of -40°C to 125°C. This component serves as a power management IC for efficient voltage regulation.
Feature Summary
- Synchronous buck topology for high-efficiency voltage conversion
- Integrated voltage mode PWM control architecture
- Built-in soft start and enable pin for controlled startup sequences
Applications
- General-purpose DC-DC step-down power supplies
- Embedded system voltage regulation
- Industrial control power modules
Procurement Notes
Verify the exact suffix against official Semtech documentation, as variants like SC2608ASTRT exist. Confirm current availability status, as specific listings indicate this product line may be discontinued or obsolete. Ensure the ordering part number matches the required package and tape/reel specifications before finalizing procurement orders.
Selection Notes
Select this controller when a simple synchronous buck solution with a 250kHz frequency is required. It is suitable for designs needing a 4.5V to 14V input range and positive output configuration. Consider the 8-SOIC package constraints and thermal requirements for the -40°C to 125°C operating range during PCB layout and component selection.
Part Context
The SC2608 series belongs to Semtech's portfolio of simple, synchronous voltage mode PWM controllers. These devices are engineered to provide efficient power management in compact form factors. The SC2608ASTRT specifically utilizes an 8-SOIC package, aligning with industry standards for space-constrained power electronics applications requiring reliable step-down regulation.
Replacement Considerations
Publicly confirmed substitute part numbers for SC2608STRT were not found in the provided source material. Verify compatibility with alternative synchronous buck controllers based on electrical parameters and pinout configurations.
