TPS61197DR

Overview

The TPS61197DR is a single-string white-LED driver designed for LCD TV applications. It features an adaptive boost output capable of reaching up to 300V, with an input supply range of 8V to 30V. The device supports programmable switching frequencies from 50kHz to 800kHz and offers high-precision PWM dimming resolution. Packaged in a 16-SOIC case, it operates within a temperature range of -40°C to 85°C.

Feature Summary

Adaptive boost output technology adjusts voltage to match white-LED requirements
High-precision pulse-width modulation dimming control for accurate brightness adjustment
Programmable switching frequency allows optimization for efficiency and component size

Applications

Single-string white LED backlighting for LCD televisions
High-voltage LED string driving in display panels
Portable electronic displays requiring efficient LED power management

Procurement Notes

Verify the specific suffix 'DR' corresponds to the tape-and-reel packaging configuration as defined by Texas Instruments. Confirm that the 16-SOIC package dimensions align with your PCB footprint requirements. Ensure the operating voltage range of 8V to 30V matches your system's power supply capabilities before finalizing procurement.

Selection Notes

Select this component when a single-channel high-voltage LED driver is required for large LCD panels. The adaptive boost feature simplifies design by automatically adjusting to LED forward voltage variations. Consider the programmable frequency range if electromagnetic interference constraints or inductor size limitations are critical factors in your application design.

Part Context

This part belongs to the Texas Instruments LED Lighting Drivers category, specifically engineered for display backlighting solutions. It serves as a specialized solution for single-string configurations, distinguishing itself from multi-channel drivers used in smaller mobile devices. The device integrates necessary control logic for stable LED operation in television-grade displays.
