LT8306RS6#TRPBF

Overview

The LT8306RS6#TRPBF is a micropower isolated flyback controller housed in a 6-lead ThinSOT package. It operates with an input voltage range of 4.5V to 60V and supports switching frequencies from 10kHz to 400kHz. The device regulates output by sampling the primary-side flyback waveform, eliminating the need for optocouplers or tertiary windings. It features boundary mode operation for compact magnetic solutions and low ripple burst mode for high efficiency at light loads. Internal compensation and soft start reduce external component count.

Feature Summary

• Primary-side regulation eliminates optocouplers and tertiary windings
• Low ripple burst mode maintains high efficiency at light loads
• Boundary mode operation enables compact magnetic designs
• Integrated internal compensation and soft start

Applications

• Isolated AC-DC power supplies
• Battery chargers
• Industrial control systems

Procurement Notes

Verify the exact suffix matches the required tape-and-reel packaging configuration. Confirm that the TSOT-23-6 package dimensions align with the target PCB footprint. Ensure the supplier provides valid traceability documentation for Analog Devices Inc. components to guarantee authenticity and quality standards.

Selection Notes

Select this controller when design constraints require minimizing bill-of-materials complexity by removing isolation feedback components. It is suitable for applications demanding high efficiency across varying load conditions without sacrificing transient response performance.

Part Context

This part belongs to the LT8306 family of micropower isolated flyback controllers. It shares core architectural features with other variants in the series but differs in specific package options and thermal characteristics defined by the RS6 designation.
