LT8306RS6#WTRPBF

Overview

The LT8306RS6#WTRPBF is a micropower isolated flyback controller from Analog Devices, housed in a TSOT-23-6 package. It operates with an input voltage range of 4.5V to 60V and supports switching frequencies between 10kHz and 400kHz. The device utilizes primary-side regulation by sampling the anti-regulation waveform directly from the primary side, 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.

Feature Summary

• Eliminates optocouplers and tertiary windings through direct primary-side voltage sampling
• Provides boundary mode operation for compact magnetic design and excellent load regulation
• Maintains high efficiency at light loads while minimizing output voltage ripple via burst mode
• Integrates internal compensation and soft-start to reduce external component count

Applications

• Isolated power supplies requiring minimal component count
• Battery chargers and adapters with strict size constraints
• Industrial control systems needing reliable isolation without feedback loops
• Consumer electronics utilizing small form factor AC-DC converters

Procurement Notes

Verify that the ordering suffix matches the required tape-and-reel configuration for automated assembly processes. Confirm the specific package variant aligns with PCB footprint requirements. Ensure compatibility with the intended switching frequency range and input voltage specifications before finalizing procurement orders.

Selection Notes

Select this controller when designing isolated flyback converters that require high integration and reduced bill of materials.
