DC DC Switching Controllers Procurement Notes

Verify the specific suffix EFE against the official datasheet to confirm the package type and temperature grade match your design requirements. Ensure that the ordering information aligns with the manufacturer's latest documentation to avoid discrepancies in pinout or electrical characteristics during procurement.

DC DC Switching Controllers Selection Notes

Select this component when a synchronous boost controller is required for inputs up to 60V. Consider the 28-TSSOP-EP package for thermal performance and board space constraints. Verify that the external component selection supports the desired switching frequency range and output voltage specifications defined in the application circuit guidelines.

DC DC Switching Controllers Part Context

This part belongs to the LTC3769 family of low IQ synchronous boost controllers from Analog Devices. The family is designed for applications demanding high efficiency and low quiescent current. The specific model differs from other variants primarily through its package configuration and industrial temperature rating, maintaining the core boost control functionality.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include other parts within the LTC3769 family, such as the LTC3769IUF#TRPBF, provided the package difference between TSSOP and QFN is accommodated in the layout. Cross-referencing with the manufacturer's pin-compatible alternatives is recommended.
