Procurement Notes
Verify the specific suffix 'MR-G' matches the required tape-and-reel packaging configuration. Confirm ROHS3 compliance status if environmental regulations are strict. Ensure the 180 kHz switching frequency aligns with your system's EMI constraints. Cross-reference the pinout diagram from the official datasheet before PCB layout finalization.
Selection Notes
Select this part when input voltage varies around the target output level. It is suitable for applications needing both buck and boost capabilities in a single controller. Consider the 180 kHz frequency for balancing efficiency and component size. Verify compatibility with external MOSFETs regarding gate drive requirements and thermal performance.
Part Context
This component is part of Torex's XC9302 series, which focuses on versatile DC-DC conversion solutions. The series targets markets demanding high efficiency and small form factors. Torex Semiconductor specializes in CMOS power management ICs, emphasizing ultra-low power consumption and miniaturization for modern portable electronics.
Replacement Considerations
Check for direct substitutes within the XC9302 family with different output voltage settings. Compare pin-to-pin compatible controllers from other manufacturers if supply chain diversification is needed. Ensure equivalent switching frequency and control architecture for seamless integration.
