Overview
The TLC59283RGER is a Texas Instruments LED lighting driver IC featuring a boost topology and sixteen constant current output channels. It operates within an input voltage range of 3 V to 5.5 V, delivering an output current of 35 mA per channel with a maximum supply current of 11 mA. The device supports a switching frequency of 35 MHz and generates an output voltage up to 10 V. Packaged in a VQFN-24 form factor, it functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates a boost converter topology for efficient LED driving
- Provides sixteen independent constant current output channels
- Includes ON/OFF control functionality for individual channel management
Applications
- LED backlighting systems
- General LED illumination circuits
- Portable electronic display modules
Procurement Notes
Verify the specific suffix RGER confirms the reel packaging format upon ordering. Confirm that the 10 V output specification aligns with the target LED string requirements, as this differs from other variants in the series. Ensure the VQFN-24 package footprint matches the PCB layout design constraints before finalizing procurement.
Selection Notes
Select this component when a lower output voltage ceiling of 10 V is sufficient for the application, distinguishing it from the 17 V variants like the TLC5928RGER. The VQFN-24 package offers a compact solution for space-constrained designs. Evaluate the 35 mA drive capability against the total LED load requirements to ensure adequate brightness without exceeding thermal limits.
Part Context
This part belongs to the TLC59283 series, which shares the core architecture of the TLC5928 family but specifies different electrical characteristics. While the TLC5928 series typically supports higher output voltages, the TLC59283 variant is optimized for applications requiring a maximum output of 10 V. It maintains the same 16-channel configuration and VQFN-24 packaging as its counterparts.
Replacement Considerations
The TLC5928RGER serves as a direct functional substitute within the same package, though it supports a higher output voltage of 17 V. Designers must verify that the increased voltage capability does not conflict with the LED forward voltage specifications in the target circuit.
