SC2442ITSTR

Overview

The SC2442ITSTR is a dual synchronous step-down switching controller manufactured by Semtech Corporation. It operates within an input voltage range of 4.75 V to 30 V and supports a maximum switching frequency of 1.1 MHz. The device provides two independent output channels with adjustable regulation capabilities. It utilizes pulse width modulation control techniques and features a TSSOP-24 package for surface mount installation. The component is designed for industrial applications, functioning reliably across a temperature range of -40°C to +125°C.

Feature Summary

Dual-channel synchronous buck topology for efficient power conversion
Integrated current-mode control with peak current-limit protection
Supports external synchronization and clock alignment
Includes soft-start functionality and enable control

Applications

Industrial power distribution systems
Telecommunications equipment power supplies
Point-of-load regulation modules
Automotive electronics subsystems

Procurement Notes

Verify the specific suffix ITSTR against official Semtech documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for the TSSOP-24 configuration. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

Selection Notes

Select this component when dual isolated or non-isolated low-voltage outputs are required from a higher voltage rail. Consider the 1.1 MHz switching frequency for balancing efficiency and passive component size. Evaluate thermal performance requirements given the operating temperature limits and package constraints.

Part Context
