IXCY100M45

Current Regulation/Management Overview

The IXCY100M45 is a high-voltage current regulator from the IXC series, manufactured by IXYS. It operates with a maximum supply voltage of 450 V and requires a minimum operating voltage of 20 V. The device maintains a low quiescent operating power supply current of 25 uA. It supports an input voltage range up to 450 V and is designed for through-hole installation in a TO-252AA package. The component functions as a non-switchable, two-terminal current regulator suitable for both AC and DC applications.

Current Regulation/Management Feature Summary

• Provides stable current regulation without switching functionality
• Operates effectively in both AC and DC circuit environments
• Features low standby current consumption for energy efficiency

Current Regulation/Management Applications

• High voltage current limiting circuits
• LED driver constant current sources
• Industrial control system protection

Current Regulation/Management Procurement Notes

Verify the specific package variant against the datasheet, as listings may reference TO-220 or TO-252AA forms. Confirm the manufacturer designation reflects the current Littelfuse ownership structure. Ensure the ordering suffix matches the required thermal and mechanical specifications for your assembly process before finalizing procurement.

Current Regulation/Management Selection Notes

Select this component when a simple, two-terminal solution for high-voltage current regulation is required. It is appropriate for designs needing minimal external components and low quiescent current draw. Evaluate the 450 V rating against peak line voltages to ensure adequate headroom for the specific application environment.

Current Regulation/Management Part Context

This device belongs to the IXC series of high-voltage current regulators. These components are characterized by their non-switchable nature and ability to handle significant voltage drops while maintaining consistent current flow. They serve as robust alternatives to more complex active regulation circuits in high-voltage power management tasks.
