LT3001IS5#TRPBF

Overview

The LT3001IS5#TRPBF is a micropower, no-optocoupler isolated flyback converter manufactured by Analog Devices Inc. It integrates the controller and power switch to provide galvanic isolation without requiring an optocoupler or feedback winding. The device supports input voltages up to 36V and delivers regulated output power up to 4W. It operates in a fixed switching frequency mode to simplify external component selection. The IS5 suffix indicates a specific temperature range and package variant within the LT8301 family architecture.

Feature Summary

• Eliminates the need for optocouplers and auxiliary windings through proprietary regulation techniques
• Integrates high-voltage power switch and control logic for compact design
• Provides stable isolated DC-DC conversion with minimal external components

Applications

• Industrial sensor isolation
• Medical equipment signal isolation
• Telecommunications interface circuits

Procurement Notes

Verify the exact suffix configuration against the manufacturer datasheet to ensure compatibility with required thermal and electrical specifications. Confirm RoHS compliance status and lead times directly with authorized distributors as availability fluctuates. Ensure the selected package variant matches the PCB footprint requirements for the TSOT-23-5 form factor.

Selection Notes

Select this component when designing isolated power supplies requiring low part count and high reliability. It is suitable for applications where space constraints prohibit traditional transformer designs with feedback loops. Consider the maximum output power limits and input voltage range to ensure adequate headroom for the specific load requirements.

Part Context

This part belongs to the LT8301 series of micropower isolated flyback converters. It shares architectural similarities with the LT8300 and LT8302 but is optimized for lower power levels up to 4W. The IS5 package designation denotes a specific thermal grade and pinout configuration distinct from standard industrial variants.

Replacement Considerations

Direct replacements include the LT8300IS5#TRPBF for similar functionality with different power ratings. Verify pin-to-pin compatibility and thermal performance before substitution. Alternative solutions may require redesigning the transformer and feedback network.
