Overview
The LT8304ES8E-1#TRPBF is a high voltage isolated flyback converter from Analog Devices. It supports an input voltage range of 3V to 100V and delivers up to 2A output current with adjustable output voltages up to 150V. The device operates at a switching frequency of 350kHz and features a low quiescent current of 390µA. Packaged in an 8-SOIC (EP) surface-mount package, it functions as a complete power solution without requiring an optocoupler.
Feature Summary
- Eliminates the need for optocouplers and traditional feedback loops through integrated isolation sensing
- Supports wide input voltage ranges suitable for industrial and automotive applications
- Provides flexible output configurations including positive or negative isolated outputs
Applications
- Industrial control systems requiring isolated power supplies
- Automotive electronics with high-voltage input requirements
- Medical equipment needing galvanic isolation
Procurement Notes
Verify the specific suffix -1 indicates the maximum output voltage rating of 150V. Confirm the ES8E package variant matches your PCB footprint requirements. Check for RoHS compliance status on the official datasheet before finalizing procurement specifications.
Selection Notes
Select this component when designing isolated flyback converters that require high input voltages up to 100V. Ensure the thermal performance of the SOIC-8 EP package meets your application's heat dissipation needs. Verify that the 350kHz switching frequency aligns with your electromagnetic interference constraints.
Part Context
This part belongs to the LT8304 family of no-opto isolated flyback converters. It shares architectural similarities with other members like the LT8302 and LT8303 but offers higher voltage and current capabilities. The family focuses on simplifying isolated power supply designs by removing feedback components.
Replacement Considerations
LT8304IS8E-1#PBF is a tube-packaged equivalent. LT8302ES8E-3#TRPBF offers similar functionality but with lower voltage ratings. Verify pin compatibility and electrical parameters before substituting.
