LED Driver IC Procurement Notes

Verify the specific suffix '24' indicates the 24V overvoltage protection rating when sourcing replacements. Confirm the 'C' variant designation matches required temperature or feature specifications. Ensure the 8-MLF package footprint aligns with existing PCB layouts. Check manufacturer documentation for humidity sensitivity handling requirements during assembly.

LED Driver IC Selection Notes

Select this component for designs requiring a compact, high-frequency boost converter for white LEDs. The 24V OVP rating suits applications with higher LED string voltages. Consider the 750mA current limit and 1.2MHz frequency for EMI and efficiency trade-offs. Verify compatibility with system dimming interfaces before finalizing the design.

LED Driver IC Part Context

This part belongs to the MIC2287 family of LED drivers from Microchip Technology. Variants like MIC2287-15YML-TR and MIC2287-24YML-TR differ primarily in their overvoltage protection thresholds. The MIC2287C series specifically targets constant-current white LED applications using a boost topology.

LED Driver IC Replacement Considerations

MIC2287-24YML-TR is a confirmed alternate designation for the same component. MIC2287C-15YML-TR is a similar device but with different overvoltage protection ratings; verify voltage headroom compatibility.
