TPS61195RUYR

Overview

The TPS61195RUYR is an integrated LED driver IC designed for large-size LCD backlighting applications. It features a boost topology with an internal 2.5A, 50V MOSFET and supports up to 8 channels, driving 96 white LEDs at 30mA per channel. The device accepts an input voltage range of 4.5V to 21V and provides a regulated output between 4.5V and 45V. It operates with a programmable switching frequency from 600kHz to 1MHz and includes PWM dimming control alongside an SMBus interface for configuration.

Feature Summary

• Integrates an adaptive boost converter with a high-voltage internal switch for efficient WLED driving
• Supports multi-channel architecture capable of driving up to 96 LEDs across 8 independent outputs
• Enables precise brightness control through hardware PWM dimming and digital SMBus configuration

Applications

• Large-size LCD panel backlighting systems
• White LED driver circuits for display modules
• Portable electronic devices requiring high-efficiency backlight power management

Procurement Notes

Verify the specific suffix (RUYR) against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure that the required SMBus address settings and PWM duty cycle limits align with your system design constraints before finalizing procurement decisions.

Selection Notes

Select this component when designing for large displays requiring high current capacity and multiple LED strings. The integrated MOSFET eliminates external switch requirements, while the wide input voltage range accommodates various battery or supply configurations. Consider the thermal performance of the exposed pad package in high-density layouts.

Part Context

This part belongs to Texas Instruments' TPS61195 family of WLED drivers. It is specifically engineered for complex backlighting solutions where space efficiency and high channel counts are critical. The device replaces discrete boost controllers and driver arrays by integrating power switching and regulation logic into a single compact package.

Replacement Considerations

Consult the official TI replacement matrix for direct equivalents. Verify that any substitute maintains the 28-WQFN footprint and supports the required 8-channel output configuration without altering the SMBus communication protocol.
