TPS61196PWPT

Overview

The TPS61196PWPT is a Texas Instruments LED lighting driver IC designed for white LED (WLED) backlight applications. It features six independent output channels, each capable of delivering up to 400 mA. The device operates with an input voltage range of 8 V to 30 V and supports PWM dimming control for each string independently. It utilizes a boost topology with an internal switching frequency of 800 kHz. The component is housed in a 28-pin PowerTSSOP package and functions within a temperature range of -40°C to 85°C.

Feature Summary

Supports six independent LED strings with individual current regulation
Enables per-string pulse-width modulation dimming control
Integrates high-frequency boost converter operation at 800 kHz

Applications

LCD backlight systems for portable devices
White LED illumination arrays
Display backlighting modules requiring independent channel control

Procurement Notes

Verify the specific suffix 'PWP' confirms the 28-pin HTSSOP package configuration. Ensure the order matches the required tape-and-reel quantity specifications provided by the manufacturer. Confirm that the application environment remains within the specified operating temperature limits. Check for any recent product change notifications regarding marking or assembly updates.

Selection Notes

Select this component when designing systems requiring precise current regulation across multiple LED strings. It is suitable for applications needing independent dimming capabilities per channel. Consider the 800 kHz switching frequency for EMI management and board space constraints. Ensure the input voltage supply aligns with the 8 V to 30 V operational range.

Part Context

This part belongs to the TPS61196 family of WLED drivers from Texas Instruments. It is specifically engineered for multi-string LED configurations where uniform brightness and independent control are critical. The device integrates necessary power stage components to simplify the design of efficient backlight solutions.
