TPS68000DBTR

Lighting, Ballast Controllers Overview

The TPS68000DBTR is a highly efficient phase-shift full-bridge controller designed for Cold Cathode Fluorescent Lamp (CCFL) applications. It operates within a frequency range of 30kHz to 100kHz and supports a supply voltage of 8V to 30V. The device is housed in a 30-TSSOP package with a surface-mount installation type. It features integrated dimming capabilities and functions as a lamp intensity control driver. The component is rated for an operating temperature range of -40°C to 85°C.

Lighting, Ballast Controllers Feature Summary

• Implements phase-shift full-bridge topology for high-efficiency CCFL inversion
• Provides integrated digital dimming control for lamp intensity adjustment
• Supports variable frequency operation between 30kHz and 100kHz

Lighting, Ballast Controllers Applications

• CCFL backlight drivers for LCD displays
• Lamp intensity control systems
• Phase-shift full-bridge inverter circuits

Lighting, Ballast Controllers Procurement Notes

Verify the specific suffix 'DBTR' confirms the tape-and-reel packaging variant, distinct from tube-packaged versions like DBT. Confirm RoHS3 compliance status if required by project specifications. Check current design recommendations as some sources indicate this part may not be recommended for new designs due to potential minimum order quantity restrictions or lifecycle status changes. Ensure the supplier documentation matches the exact Texas Instruments part number to avoid substitution errors.

Lighting, Ballast Controllers Selection Notes

Select this component when a dedicated phase-shift full-bridge controller is required for CCFL applications. It is suitable for designs needing integrated dimming functionality without external microcontroller intervention for basic control. Consider the 30-TSSOP package constraints and the 8V-30V input range compatibility with the system power architecture. Evaluate thermal performance within the specified -40°C to 85°C operating window.
