Procurement Notes
Verify the specific suffix 'Y' against official Texas Instruments documentation to confirm pinout, marking, or tape-and-reel specifications. Ensure the WSON-6 package variant matches the design requirements. Cross-reference the datasheet revision date to validate all electrical parameters before finalizing procurement orders.
Selection Notes
Select this component when designing compact LED drivers requiring high-frequency operation between 1.2 MHz and 2 MHz. It is suitable for low-voltage input sources ranging from 2.7 V to 5.5 V. Consider the WSON-6 package for space-constrained layouts. Verify that the required output voltage does not exceed 24 V and that the load current remains within the 2.8 A limit.
Part Context
