TLC5927IDWR

Overview

The TLC5927IDWR is a Texas Instruments LED lighting driver IC featuring 16 constant-current sink outputs. It operates on a 3 V to 5.5 V supply and utilizes a boost topology to drive LEDs with up to 120 mA per channel at voltages reaching 17 V. The device supports a 30 MHz clock frequency and is housed in a 24-pin SOIC package.

Feature Summary

• Provides 16 individually addressable constant-current sink channels for precise LED control
• Integrates an internal boost converter to enable high-voltage LED driving from low supply voltages
• Supports serial data input via standard SPI-compatible interface for simplified system integration

Applications

• Portable electronic device backlighting systems
• General-purpose LED indicator arrays
• Low-power LED illumination modules

Procurement Notes

Verify the specific suffix 'IDWR' corresponds to the SOIC-24 package variant rather than the DBQR QSOP version. Confirm RoHS compliance status and ensure the operating temperature range meets -40°C to +125°C requirements for your specific application environment before finalizing procurement.

Selection Notes

Select this component when 16-channel constant current control is required within a compact SOIC footprint. It is suitable for applications needing high brightness uniformity across multiple LEDs without external current-setting resistors, provided the total power dissipation remains within thermal limits.

Part Context

This part belongs to the TLC592x family of LED drivers designed for portable electronics. Unlike linear-only drivers, it incorporates a boost regulator, allowing efficient operation from single-cell lithium batteries or 3V logic supplies while maintaining consistent LED brightness regardless of forward voltage variations.

Replacement Considerations

TLC5927IDBQR: Identical functional specifications but packaged in a 24-pin QSOP instead of SOIC.
