DC DC Switching Controllers Procurement Notes

Verify the specific suffix '#PBF' indicates lead-free compliance and RoHS status when ordering. Confirm the 'IS' grade meets the required industrial temperature range specifications. Ensure the 16-SOIC package dimensions align with your PCB footprint requirements. Cross-reference the manufacturer part number directly with official Analog Devices documentation to avoid counterfeit components.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring flexible topology support between buck and boost configurations. The integrated Burst Mode makes it suitable for battery-operated devices where standby current minimization is critical. Consider the 400kHz switching frequency when designing passive components for size constraints. Verify that the external MOSFET selection matches the drive capabilities of the controller.

DC DC Switching Controllers Part Context

The LTC1266 series comprises synchronous switching regulator controllers designed for versatile power conversion needs. This family allows designers to implement efficient step-down or step-up converters using external power switches. The inclusion of automatic Burst Mode distinguishes these controllers by optimizing performance across varying load conditions without requiring complex external circuitry.

DC DC Switching Controllers Replacement Considerations

Consult Analog Devices documentation for direct cross-references within the LTC1266 family, such as the LTC1266IS#PBF or LTC1266ACS#TRPBF. Verify pinout compatibility and electrical parameter equivalence before substitution. Note that packaging variations may exist between tube and tape-and-reel options.
