LT1576CS8

Overview

The LT1576CS8 is a monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 4V to 30V and provides a fixed output voltage of 5V. The device integrates a high-current switch capable of delivering up to 2A of continuous load current. Designed for efficiency, it utilizes a constant-frequency architecture with a typical switching frequency of 200kHz. The component is housed in an 8-pin SOIC package and supports surface-mount installation.

Feature Summary

• Integrates a 2A power switch within the monolithic die structure
• Utilizes constant-frequency pulse-width modulation topology
• Includes internal oscillator and control logic circuitry

Applications

• Point-of-load regulation modules
• Battery-powered systems requiring efficient step-down conversion
• General-purpose DC/DC conversion circuits

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and thermal characteristics. Ensure that the selected variant matches the required operating temperature range and packaging specifications for the intended design environment before finalizing procurement.

Selection Notes

Select this component when a fixed 5V output is required from a 4V to 30V input source. Consider the integrated 2A switch capability for moderate load applications. Evaluate external component requirements for the 200kHz switching frequency to ensure proper filtering and stability are achieved in the target circuit design.

Part Context

This part belongs to the LT1576 family of switching regulators designed for high-efficiency power management. The CS8 designation indicates a commercial temperature grade version packaged in an 8-lead Small Outline Integrated Circuit (SOIC) format suitable for automated surface-mount assembly processes.
