Overview
The LT8316IF#TRPBF is a micropower, high voltage flyback controller manufactured by Analog Devices Inc. It supports a maximum input voltage of 600V and operates with a switching frequency up to 140 kHz. The device provides one output channel capable of delivering 12 V at 2 A. Designed for surface mount installation, it utilizes a TSSOP-20 package. The operational temperature range spans from -40°C to +125°C. This component functions as a DC-DC switching controller within the PMIC category, featuring quasi-resonant boundary mode operation to enhance efficiency.
Feature Summary
- Eliminates the need for an opto-isolator by sampling output voltage directly from the primary side for regulation.
- Supports isolated no-opto flyback topology with integrated synchronous rectifier control.
- Features quasi-resonant boundary mode operation to improve load regulation and reduce transformer size.
- Includes built-in current limit, enable, and soft-start control characteristics.
Applications
- High voltage isolated power supplies
- Industrial AC/DC offline switch-mode power supplies
- Battery charger systems requiring isolation
Procurement Notes
Verify availability status carefully, as this specific part number may be subject to limited supply or factory special order conditions. Confirm that the TSSOP-20 package matches your PCB footprint requirements. Ensure the 600V input rating aligns with your system's electrical design constraints before finalizing procurement decisions.
Selection Notes
Select this controller when designing high-voltage isolated flyback converters that require simplified feedback loops without optocouplers. Consider the 140 kHz switching frequency for magnetic component sizing. Verify thermal performance within the specified -40°C to +125°C operating range for your intended application environment.
Part Context
This component belongs to the LT8316 series of micropower controllers. It is distinct from other variants like the LT8316HFE#TRPBF which may have different temperature ratings or packaging options. The IF suffix typically denotes specific industrial grade specifications within the Analog Devices portfolio.
Replacement Considerations
Direct substitutes include other LT8316 variants such as LT8316HFE#TRPBF, though pinout compatibility and temperature ranges must be verified against official datasheets before substitution.
FAQ
Does the LT8316IF#TRPBF require an opto-isolator for output regulation?
No, the device samples the output voltage from the primary side, eliminating the need for an opto-isolator.
What is the maximum input voltage supported by this controller?
The LT8316IF#TRPBF supports a maximum input voltage of 600V.
