ILD8150XUMA1

Overview

The ILD8150XUMA1 is an 80V DC-DC buck LED driver IC from Infineon Technologies, designed for high-efficiency lighting applications. It supports a maximum output current of 1.5A and operates within a supply voltage range of 8V to 80V. The device features a switching frequency up to 2MHz and offers hybrid dimming capabilities down to 0.5%. Packaged in an 8-pin DSO (PG-DSO-8) surface-mount format, it integrates internal power switches and provides comprehensive protection against over-temperature, over-voltage, and over-current conditions.

Feature Summary

• Integrates high-side power switch for compact buck topology design
• Supports hybrid dimming with high linearity and low minimum levels
• Includes built-in thermal, over-voltage, and over-current protection mechanisms

Applications

• High-power LED lighting systems
• Ultra-high power LED arrays
• Adjustable white light systems
• Multi-channel LED drivers

Procurement Notes

Verify the specific suffix XUMA1 corresponds to the tape-and-reel packaging configuration required for your assembly process. Confirm that the PG-DSO-8 package dimensions align with your PCB footprint specifications. Ensure input voltage requirements fall within the 8V to 80V operational range defined in the datasheet. Check for RoHS compliance status if environmental regulations apply to your manufacturing site.

Selection Notes

Select this component when designing buck converter topologies requiring integrated power switches and high efficiency. It is suitable for applications demanding precise current regulation up to 1.5A. Consider its hybrid dimming capability if analog and PWM control are needed simultaneously. Evaluate the 2MHz switching frequency for potential size reduction in external passive components compared to lower-frequency alternatives.

Part Context

This part belongs to the ILD series of DC-DC LED driver ICs from Infineon Technologies. These devices are engineered for smart lighting solutions, emphasizing high efficiency and safety margins near SELV limits. The ILD8150 variant specifically targets mid-to-ultra-high power applications, distinguishing itself through integrated protection features and flexible dimming options within a compact surface-mount package.

Replacement Considerations

Consult official Infineon documentation for direct pin-compatible substitutes or functional equivalents within the ILD family. Verify electrical parameters such as maximum current and voltage ratings before substituting. Cross-reference package types to ensure mechanical compatibility without redesigning the PCB layout.
