UCC3305DW

Overview

The UCC3305DW is a high-intensity discharge (HID) lamp controller manufactured by Texas Instruments. It operates within an input voltage range of 5 V to 18 V and supports a switching frequency between 80 kHz and 120 kHz. The device provides regulated output current for HID applications, featuring soft start capabilities and open lamp detection. It is housed in a 28-pin SOIC package and is designed for full bridge module configurations.

Feature Summary

• Integrated control for high-intensity discharge lamps with intensity regulation
• Built-in protection mechanisms including open lamp detection
• Soft start functionality to manage initial lamp ignition

Applications

• High-intensity discharge lighting systems
• Automotive headlamp controllers
• Industrial HID ballast designs

Procurement Notes

Verify the specific revision code on the datasheet before procurement, as component specifications may vary between revisions. Confirm that the 28-pin SOIC package dimensions match your PCB footprint requirements. Ensure the operating temperature range aligns with your system's thermal environment. Check for any obsolete status notifications from the manufacturer prior to finalizing design-in decisions.

Selection Notes

Select this component when designing HID lighting circuits requiring integrated control features. It is suitable for applications needing precise current regulation and lamp fault detection. Consider the 28-pin SOIC package size relative to available board space. Evaluate the 80 kHz to 120 kHz switching frequency against electromagnetic interference constraints in your specific application environment.

Part Context

This part belongs to Texas Instruments' family of lighting and ballast controllers. It is specifically engineered for HID lamp applications, distinguishing itself from general-purpose power management ICs. The device integrates control logic necessary for stable HID operation, reducing the need for external discrete components in standard lighting designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternative HID controllers from other manufacturers.
