LT1768IGN#TRPBF

Lighting, Ballast Controllers Overview

The LT1768IGN#TRPBF is a single-channel cold cathode fluorescent lamp (CCFL) controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 9V to 24V and draws a typical supply current of 7 mA. The device supports switching frequencies between 300 kHz and 410 kHz, enabling efficient control for backlighting applications. It is housed in a 16-lead SSOP surface-mount package and functions reliably across an extended temperature range from -40°C to 125°C.

Lighting, Ballast Controllers Feature Summary

• Integrates a multimode dimming scheme that combines linear and PWM techniques for precise brightness control
• Designed specifically for controlling single or multiple CCFL displays with high efficiency
• Supports automotive-grade operation with extended thermal stability

Lighting, Ballast Controllers Applications

• Single or multiple CCFL display backlighting systems
• Automotive instrument cluster illumination
• Industrial LCD panel lighting controllers

Lighting, Ballast Controllers Procurement Notes

Verify the component matches the specific LT1768 family specifications before integration. Confirm the suffix #TRPBF indicates tape-and-reel packaging suitable for automated assembly processes. Ensure the supplier provides valid traceability documentation consistent with Analog Devices manufacturing standards. Cross-reference the datasheet revision date to confirm compatibility with current design requirements.

Lighting, Ballast Controllers Selection Notes

Select this component when designing systems requiring dedicated CCFL driver functionality with integrated dimming capabilities. The fixed frequency range of 300 kHz to 410 kHz suits applications where electromagnetic interference must be managed within specific bands. Consider the 16-SSOP package constraints for PCB layout space and thermal dissipation needs relative to the target enclosure design.

Lighting, Ballast Controllers Part Context

This part belongs to the LT1768 series of lighting controllers, which are optimized for cold cathode fluorescent lamps. The IGN suffix denotes the industrial temperature grade and SSOP package type, while TRPBF specifies the reel packaging format. It serves as a specialized solution for display backlighting compared to general-purpose LED drivers.
