Overview
The LT8306RS6#TRMPBF is a micropower isolated flyback controller in a TSOT-23-6 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 magnetics and low ripple burst mode for light-load efficiency. 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 solutions
- Integrated internal compensation and soft-start functionality
Applications
- Isolated AC-DC power supplies
- Battery chargers
- Industrial control systems
- Consumer electronics adapters
Procurement Notes
Verify the specific suffix #TRMPBF against official Analog Devices documentation to confirm tape-and-reel packaging and lead-free status. Ensure the part number matches the exact datasheet revision required for your design. Cross-reference the manufacturer's current lifecycle status to avoid obsolescence risks during production planning.
Selection Notes
Select this controller when isolation via optocouplers is undesirable due to cost or space constraints. It is suitable for applications requiring wide input voltage ranges up to 60V. Consider the TSOT-23-6 package size for tight board layouts. Evaluate thermal performance requirements as the device integrates the driver for the external N-channel MOSFET.
Part Context
This component belongs to the LT8306 family of micropower isolated flyback controllers. It shares architectural similarities with other primary-side regulation devices but is distinct in its specific pinout and package configuration. The RS6 designation indicates the TSOT-23-6 package variant, differentiating it from other footprint options within the broader product line.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing transformer designs if considering alternative primary-side regulation controllers.
