Overview
The LT8304HS8E#TRPBF is a micropower isolated flyback converter from Analog Devices, housed in an 8-lead SOIC package with an exposed pad. It operates with an input voltage range of 3V to 100V and delivers up to 2A of switch current. The device features a fixed switching frequency of 350kHz and a typical quiescent current of 390µA. Designed for high-voltage applications, it supports output voltages up to 150V. The component functions as a positive or negative isolation-capable adjustable regulator with one output.
Feature Summary
- Integrates primary-side sensing to eliminate the need for optocouplers and error amplifiers
- Supports wide input voltage ranges suitable for high-voltage DC-DC conversion
- Features low quiescent current operation for enhanced efficiency in standby modes
Applications
- Industrial power supplies requiring galvanic isolation
- Battery chargers for high-voltage systems
- Telecommunications equipment power stages
Procurement Notes
Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure the procurement channel provides valid traceability for this PMIC category. Confirm RoHS compliance status directly from the manufacturer's latest release notes before integration into production schedules.
Selection Notes
Select this component when designing isolated flyback converters that require primary-side regulation to reduce bill-of-materials complexity. It is appropriate for applications needing high input voltage tolerance without external feedback loops. Consider the thermal performance of the exposed pad package for heat dissipation requirements in compact designs.
Part Context
This part belongs to the LT8304 family of micropower isolated flyback converters. It shares architectural similarities with the LT8304-1 but may differ in specific electrical tolerances or pin configurations. The series is designed to simplify isolated power supply design by integrating control logic and power switches into a single monolithic IC.
Replacement Considerations
The LT8304HS8E-1#TRPBF is a related variant within the same family. Verify functional equivalence and pin compatibility before substitution. Consult the official datasheet for detailed comparison of electrical parameters between these specific part numbers.
