Overview
The LT8304IS8E#TRPBF is a micropower isolated flyback converter from Analog Devices, housed in an 8-SOIC package with an exposed pad. It accepts input voltages between 3 V and 100 V and provides a single adjustable output ranging from 1 V to 150 V. The device supports up to 2 A of switch current and operates at switching frequencies up to 350 kHz. It features a low quiescent current of 390 uA and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Eliminates the need for optocouplers by sampling the isolated output voltage directly from the primary-side flyback winding.
- Supports both positive and negative output configurations while maintaining galvanic isolation.
- Integrates a high-voltage switch capable of handling 150 V and 2 A for robust power delivery.
Applications
- Industrial control systems requiring isolated power supplies
- Medical equipment needing safe isolated DC-DC conversion
- Telecommunications infrastructure power management
Procurement Notes
Verify the specific suffix #TRPBF confirms tape-and-reel packaging rather than tube packaging when sourcing components. Confirm the manufacturer is Analog Devices Inc. and check RoHS compliance status. Ensure the part number matches the exact electrical specifications required for your design before finalizing orders.
Selection Notes
Select this component for designs requiring high input voltage ranges up to 100 V without external biasing. It is suitable for applications prioritizing board space reduction by removing optocouplers. Consider the 8-SOIC-EP package for thermal management needs in compact layouts.
Part Context
This part belongs to the LT8304 family of no-opto isolated flyback converters. It shares core architecture with variants like the LT8304IS8E-1 but differs in packaging or specific operational parameters defined by the manufacturer's coding system.
Replacement Considerations
LT8304IS8E#PBF is a tube-packaged equivalent. LT8304ES8E#TRPBF is a commercial grade variant. Verify pinout compatibility and thermal performance when substituting.
FAQ
Does the LT8304IS8E#TRPBF require an optocoupler for feedback?
No, it samples the output voltage directly from the primary side, eliminating the need for an optocoupler.
What is the maximum input voltage supported?
The device supports a maximum input voltage of 100 V.
