LED Driver IC Procurement Notes

Verify the specific suffix (e.g., TR for tape and reel) against your manufacturing requirements. Confirm that the 16-TSSOP-EP footprint matches your PCB layout. Ensure the input voltage supply stays within the 4.5V to 20V limit. Check thermal design adequacy for the exposed pad implementation. Validate compatibility with your system's PWM dimming signal levels.

LED Driver IC Selection Notes

Choose this component when a single-channel boost driver with integrated FET is required. It is suitable for applications needing up to 3.5A switch current. Consider the 1MHz frequency for inductor size optimization. Verify that the operating temperature range meets environmental constraints. Ensure the TSSOP-16 package fits the available board space.
