LT8316HFE#PBF

Overview

The LT8316HFE#PBF is a micropower, high-voltage flyback controller from Analog Devices. It operates with an input voltage range of 18 V to 560 V and delivers up to 300 mA output current at 630 V. The device features a quiescent current of 70 uA and a switching frequency of 140 kHz. It eliminates the need for opto-isolators by sampling secondary-side voltage through the transformer's tertiary winding. Operating temperatures span from -40°C to +150°C. The component is housed in a 20-TSSOP-EP package.

Feature Summary

Eliminates the requirement for opto-isolators for regulation by sampling output voltage directly from the transformer's tertiary winding.
Supports high-voltage applications with input ranges extending up to 560 V and output capabilities reaching 630 V.
Features micropower operation with low static current consumption to enhance efficiency in standby modes.

Applications

High-voltage isolated power supplies
Industrial control systems requiring galvanic isolation
Battery charging equipment

Procurement Notes

Verify the specific suffix PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the TSSOP-EP package availability matches your PCB footprint requirements. Ensure the supplier provides valid origin documentation to guarantee authenticity. Check for any recent product lifecycle notifications regarding obsolescence or replacement recommendations from Analog Devices.

Selection Notes

Select this controller for designs requiring high input voltages without opto-isolator complexity. Consider the 140 kHz switching frequency for magnetic component sizing. Evaluate thermal performance given the +150°C maximum junction temperature rating. Compare against lower voltage variants if input sources do not exceed standard levels. Verify tertiary winding accessibility on the transformer design for proper feedback sensing.

Part Context

The LT8316 belongs to the LT8315/LT8316 family of micropower high-voltage flyback controllers. These devices are designed to simplify isolated converter designs by removing the opto-isolator. The HFE#PBF designation specifies the lead-free, tape-and-reel or tube packaging variant suitable for surface-mount assembly in industrial environments.
