LTC3772ETS8#TRMPBF

DC DC Switching Controllers Overview

The LTC3772ETS8#TRMPBF is a synchronous step-down DC/DC switching controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.75V to 9.8V and delivers a positive output configuration. The device utilizes a TSOT-23-8 package and supports a fixed switching frequency of 550kHz with a maximum duty cycle of 100%. It functions as a single-output regulator controller designed for surface-mount installation.

DC DC Switching Controllers Feature Summary

• Supports 100% maximum duty cycle operation
• Integrates current limit and enable control features
• Designed for synchronous buck converter topologies

DC DC Switching Controllers Applications

• Point-of-load regulation in distributed power systems
• Battery-powered equipment requiring efficient step-down conversion
• Industrial control systems utilizing low-voltage logic supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRMPBF indicates tape-and-reel packaging when sourcing components. Confirm that the part meets RoHS3 compliance standards required for your assembly process. Ensure the supplier provides valid traceability documentation matching the manufacturer's lot codes. Cross-reference the ordering number with official distributor catalogs to avoid counterfeit inventory risks during procurement.

DC DC Switching Controllers Selection Notes

Select this component when designing compact synchronous buck converters requiring a small footprint. The TSOT-23-8 package suits space-constrained layouts compared to larger alternatives. Consider the 550kHz switching frequency for balancing efficiency and passive component size. Verify that the external MOSFET selection aligns with the controller's drive capabilities and thermal requirements.

DC DC Switching Controllers Part Context

This controller belongs to the LTC3772 family of synchronous buck regulators. It shares functional similarities with other Analog Devices PMICs but is distinct from boost controllers like the LTC3872 or multi-topology units like the LTC1772. The ETS8 designation specifies the thermal enhancement and package type, while #TRMPBF denotes the reel packaging and lead-free finish.

DC DC Switching Controllers Replacement Considerations

Direct pin-compatible substitutes are not explicitly confirmed in public documentation. Evaluate alternative Analog Devices synchronous buck controllers based on input voltage compatibility and package dimensions. Verify that any replacement maintains the required 550kHz frequency and 100% duty cycle specifications.
