Overview
The LT8316IF#PBF is a micropower, high voltage flyback controller manufactured by Analog Devices Inc. It operates with an input voltage up to 560V and features a switching frequency of 140 kHz. The device supports a single output configuration with a maximum output current of 2 A and a regulated output voltage of 12 V. It is housed in a TSSOP-20 surface-mount package and functions within a temperature range of -40°C to +125°C. This component belongs to the LT8316 series under PMIC power management ICs.
Feature Summary
- Eliminates the need for opto-isolators by sampling output voltage directly from the secondary side for regulation.
- Supports high input voltages up to 560V for isolated flyback applications.
- Designed for micropower operation to enhance efficiency in low-power systems.
Applications
- Isolated flyback converter designs requiring no opto-isolator
- High voltage input power supply systems
- Micropower industrial control applications
Procurement Notes
Verify availability status as Mouser reports limited supply or factory special order conditions for this part number. Confirm RoHS compliance details through official documentation before procurement. Ensure the specific suffix matches required packaging and temperature grade specifications for your application needs.
Selection Notes
Select this controller for applications requiring high input voltage isolation without opto-isolators. Consider the 140 kHz switching frequency and 2A output capability when designing transformer parameters. Verify thermal performance within the -40°C to +125°C operating range for your specific environment.
Part Context
The LT8316IF#PBF is part of the LT8316 family of micropower flyback controllers. It integrates primary-side regulation techniques to simplify design and reduce component count. The 'I' suffix indicates an extended industrial temperature range, while '#PBF' denotes lead-free and RoHS compliance in a TSSOP-20 package.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult Analog Devices technical support for direct replacements or pin-compatible alternatives if this specific part number is unavailable.
FAQ
