LED Driver IC Procurement Notes

Verify the specific suffix P1-13 against the manufacturer's latest datasheet to confirm packaging and tape-and-reel specifications. Confirm RoHS compliance status directly with Diodes Incorporated documentation prior to finalizing procurement orders. Ensure that the required operating temperature range aligns with the specified -40°C to +105°C limits for your intended application environment.

LED Driver IC Selection Notes

Select this component when a fixed 15 mA drive current is required for high-voltage LED strings. The boost topology makes it suitable for applications where the LED forward voltage exceeds the available supply voltage. Consider the PowerDI123-2 package size for space-constrained designs. Verify that the 20 kHz switching frequency does not interfere with sensitive analog circuits in the system.
