TLC5927IPWPR

Overview

The TLC5927IPWPR is a Texas Instruments LED lighting driver IC featuring 16 constant-current sink channels. It utilizes a boost topology to drive LEDs with an output current of 120 mA and a maximum output voltage of 17 V. The device operates on a supply voltage range of 3 V to 5.5 V, with a maximum power dissipation of 2.9 W. It supports a clock frequency of 30 MHz and functions within a temperature range of -40°C to +125°C. The component is housed in an HTSSOP-24 package.

Feature Summary

• Provides 16 independent constant-current output channels for uniform LED driving.
• Integrates thermal shutdown protection to prevent damage during overtemperature conditions.
• Supports high-speed serial data input via a 30 MHz clock frequency.

Applications

• LED display systems requiring high channel count and constant current regulation
• General LED lighting applications with variable forward voltage loads
• Portable electronic devices operating within 3 V to 5.5 V supply ranges

Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the HTSSOP-24 package and reel packaging configuration. Confirm RoHS compliance status through official documentation. Ensure the intended application environment remains within the specified -40°C to +125°C operating temperature limits to maintain device reliability and performance specifications.

Selection Notes

Select this component when 16 constant-current sink channels are required with a maximum output current of 120 mA. It is suitable for designs needing a boost topology to handle LED forward voltages up to 17 V. Consider the HTSSOP-24 package constraints and the 30 MHz clock speed requirements for data transmission rates in the target system architecture.
