SC2608ASTRT

Overview

The SC2608ASTRT is a synchronous buck switching controller manufactured by Semtech Corporation. It operates with a fixed switching frequency of 250kHz and supports a maximum duty cycle of 85%. The device accepts an input supply voltage range of 4.5V to 14V and features a single positive output configuration. It utilizes an 8-SOIC surface-mount package and functions within a junction temperature range of -40°C to 125°C.

Feature Summary

Synchronous rectification architecture for improved efficiency
Integrated soft-start functionality to limit inrush current
Phase control capability for multi-phase synchronization
Enable pin support for power management control

Applications

Point-of-load regulation in embedded systems
General DC-DC conversion for industrial electronics
Power supply stages for communication equipment

Procurement Notes

Verify component authenticity through authorized channels, as the SC2608ASTRT is listed as a discontinued product. Confirm availability of surplus stock or equivalent alternatives from verified distributors. Ensure that any replacement components meet the original electrical specifications and thermal requirements for your specific application design.

Selection Notes

Select this controller for applications requiring a 250kHz switching frequency and a 4.5V to 14V input range. The 8-SOIC package suits space-constrained designs. Consider the synchronous topology for better efficiency compared to non-synchronous alternatives. Evaluate the need for phase control if multiple units are used in parallel.

Part Context

This component belongs to the SC2608 family of power management integrated circuits. It is designed as a high-efficiency synchronous buck controller. The device integrates gate drivers and control logic to manage external power switches. It is part of Semtech's portfolio of DC-DC switching controllers aimed at providing reliable power conversion solutions.
