LT8304HS8E#PBF

Overview

The LT8304HS8E#PBF is an isolated flyback converter from Analog Devices, housed in an 8-pin SOIC-Narrow-EP package. It supports a wide input voltage range of 3 V to 100 V and delivers up to 2 A output current with a maximum switch voltage rating of 150 V. The device operates at a fixed switching frequency of 350 kHz and features a low quiescent current of 390 uA. Designed for industrial applications, it functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrated high-voltage startup circuit eliminates the need for auxiliary windings or bootstrap supplies.
• Capable of regulating positive or negative isolated outputs without requiring optocouplers.
• Includes internal synchronization to suppress audible noise and allow frequency alignment.

Applications

• Industrial power supplies
• Telecommunications systems
• Medical equipment

Procurement Notes

Verify the specific suffix against official documentation to confirm exact electrical characteristics and thermal ratings. Confirm package integrity and lead condition upon receipt. Ensure compatibility with your design's isolation requirements and thermal management strategy before finalizing procurement.

Selection Notes

Select this component when designing isolated converters requiring high input voltages up to 100 V. It is suitable for applications needing simple regulation without optocouplers. Consider the 350 kHz frequency for balancing efficiency and component size. Verify that the 150 V switch rating accommodates your transformer design and input transients.

Part Context

This part belongs to the LT8304 family of no-opto isolated flyback converters. These devices are designed to simplify power supply designs by removing the feedback loop components typically required for isolation. The HS8E variant indicates a specific thermal and electrical grade within the series.
