UCC2305DW

Overview

The UCC2305DW is an integrated HID lamp controller IC designed to manage the operation of high-intensity discharge lamps. It supports boost and flyback topologies with a supply voltage range of 5 V to 18 V. The device operates at frequencies between 80 kHz and 120 kHz, featuring soft switching capabilities. It includes functions for lamp intensity control and open lamp detection. The component is housed in a 28-SOIC package and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Integrates all necessary functions to control and drive a single HID lamp
• Provides lamp intensity control and open lamp detection capabilities
• Utilizes soft switching technology to enhance operational efficiency

Applications

• High-Intensity Discharge (HID) lamp systems
• Automotive lighting controllers
• Ballast controller circuits

Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm package type and qualification status. Ensure the ordering part number matches the required AEC-Q100 grade if automotive compliance is mandatory. Cross-reference the datasheet revision date to ensure compatibility with current design specifications and regulatory requirements.

Selection Notes

Select this component for designs requiring a single-chip solution for HID lamp management. Consider the 28-SOIC package constraints and the 5 V to 18 V input range. Evaluate thermal performance within the -40°C to +105°C operating temperature range. Confirm that the 80 kHz to 120 kHz frequency range aligns with system electromagnetic interference limits.

Part Context

This device belongs to the UCC2305 series of lighting controllers. It is specifically engineered for HID lamp applications, distinguishing it from general-purpose LED drivers. The integration of control logic and power stage management reduces external component count compared to discrete solutions.

Replacement Considerations

Consult the Texas Instruments product selection guide for direct pin-to-pin or functionally equivalent alternatives. Verify compatibility regarding package dimensions and electrical characteristics before substitution.
