L6585DTR

Lighting, Ballast Controllers Overview

The L6585DTR is a PFC and ballast controller IC manufactured by STMicroelectronics, designed for electronic lighting applications. It integrates transition mode PFC control with half-bridge ballast management in a single package. The device operates within a frequency range of 58.4kHz to 62kHz and requires a supply voltage between 11V and 16V. It draws a supply current of 7 mA and functions reliably across an extended temperature range from -40°C to +150°C. The component is housed in a 20-SOIC surface-mount package.

Lighting, Ballast Controllers Feature Summary

• Integrates transition mode PFC with over-current, over-voltage protection, and THD optimization alongside half-bridge ballast control features.
• Supports independently programmable preheating and ignition phases with smart hard switching detection and choke saturation detection.
• Includes end-of-life protection compliant with various ballast configurations and precise oscillator performance.

Lighting, Ballast Controllers Applications

• Electronic ballasts for fluorescent lamps
• Power factor correction circuits in lighting systems
• Integrated PFC and ballast control designs

Lighting, Ballast Controllers Procurement Notes

Verify the obsolete status of this component before design finalization, as it may no longer be available for new production orders. Confirm that the 20-SO package dimensions align with your PCB layout constraints. Ensure that the operating temperature range meets your specific environmental requirements. Check for valid replacement part numbers if continuity is required for existing products.

Lighting, Ballast Controllers Selection Notes

Select this component when a combined solution for power factor correction and ballast control is needed to reduce bill of materials count. It is suitable for applications requiring high efficiency and compliance with lighting standards. Consider the integrated protections against choke saturation and over-current for robust system reliability. Evaluate the thermal performance within the specified operating temperature range.

Lighting, Ballast Controllers Part Context

The L6585 series represents a family of combo ICs combining PFC and ballast controllers. The L6585DTR specifically denotes the tape and reel packaging variant of the L6585D. This integration simplifies the design of compact lighting drivers by reducing the number of discrete components required for control logic and protection circuits.

Lighting, Ballast Controllers Replacement Considerations

The product is listed as obsolete. Verify availability of alternative solutions or updated versions from the manufacturer. Consult official documentation for recommended replacements if continuing production is necessary.
