LT8304IS8E#PBF

Overview

The LT8304IS8E#PBF is an isolated flyback converter from Analog Devices, housed in an 8-SOIC-EP package. It supports a wide input voltage range of 3 V to 100 V and delivers up to 2 A output current with adjustable output voltages from 1 V to 150 V. Operating at a switching frequency of 350 kHz, the device features a quiescent current of 390 uA. It functions within a temperature range of -40°C to +125°C and includes shutdown capability.

Feature Summary

• Enables transformer isolation without requiring optocouplers or feedback components
• Supports positive or negative isolated output configurations
• Integrates high-voltage startup circuitry for direct connection to bus supplies

Applications

• Industrial power supply designs
• Battery charger systems
• Isolated DC/DC conversion modules

Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm RoHS compliance details and moisture sensitivity levels prior to assembly. Ensure storage conditions meet humidity requirements to prevent damage during handling and soldering processes.

Selection Notes

Select this model for applications requiring high input voltages up to 100 V and flexible output ranges. The absence of optocouplers simplifies design while maintaining isolation. Consider thermal management needs given the SOIC-Narrow-EP-8 package and operating temperature limits.

Part Context

This component belongs to the LT8304 series of no-opto isolated flyback converters. It shares architectural similarities with variants like LT8304IS8E-1#PBF but differs in specific suffix designations. The series targets efficient isolated power conversion in compact footprints.

Replacement Considerations

LT8304IS8E-1#PBF serves as a related variant within the same family. Verify pinout compatibility and electrical parameter alignment before substitution.
