Overview
The LT8304IS8E-1#PBF is a high-voltage isolated flyback converter IC from Analog Devices Inc., designed for applications requiring galvanic isolation without an optocoupler. It operates with an input voltage range of 3V to 100V and delivers up to 2A output current. The device supports adjustable output voltages up to 150V and features a switching frequency range of 11kHz to 350kHz. It utilizes a SOIC-Narrow-EP-8 package and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Eliminates the need for optocouplers and feedback windings through integrated primary-side regulation
- Supports wide input voltage ranges suitable for industrial and automotive power supplies
- Provides precise output voltage regulation via internal sensing mechanisms
Applications
- Industrial power supplies requiring isolated outputs
- Automotive electronics systems
- Battery charger designs
Procurement Notes
Verify the specific suffix '-1' against official datasheets to confirm it denotes the correct variant, as ordering suffixes may indicate temperature grades or packaging differences rather than functional changes. Ensure compatibility with your PCB footprint and thermal requirements before finalizing procurement.
Selection Notes
Select this component when designing isolated DC-DC converters that require simplified feedback loops and reduced bill-of-materials count. It is suitable for systems needing high input voltages and moderate output currents while maintaining tight regulation without secondary-side control circuitry.
Part Context
This part belongs to the LT8304 family of no-opto isolated flyback converters. It shares core architecture with variants like LT8304IS8E#PBF but may differ in specific electrical characteristics or qualification levels defined by the manufacturer's suffix codes.
Replacement Considerations
LT8304IS8E#PBF is a related variant within the same product family. Verify if the '-1' suffix indicates a specific revision or grade difference before substituting.
