LT3825EFE#TRPBF

Overview

The LT3825EFE#TRPBF is an isolated switching regulator controller designed for medium power flyback topologies, typically supporting applications from 10W to 60W. It features a wide input supply range and operates at a switching frequency of 250kHz. The device utilizes synchronous rectification and supports output currents up to 8A. It is housed in a 16-pin TSSOP-EP package and accepts input voltages between 36V and 72V.

Feature Summary

Isolated no-optocoupler synchronous flyback control architecture
Wide input supply voltage range capability
Integrated synchronous rectifier driver
Frequency synchronization support

Applications

Medium power isolated DC/DC conversion (10W to 60W)
Industrial power supplies
Telecommunications equipment
Medical power systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the 16-pin TSSOP-EP footprint matches the target PCB design. Ensure the application requires isolated synchronous flyback topology compatible with the 250kHz switching frequency. Cross-reference the manufacturer datasheet for thermal pad requirements and electrical specifications before finalizing procurement.

Selection Notes

Select this component for designs requiring high efficiency through synchronous rectification without optocoupler feedback latency. Consider the wide input range for robust performance across varying line conditions. Evaluate the 16-pin TSSOP-EP package for thermal dissipation needs relative to the 8A current capability. Verify compatibility with external components for the 10W to 60W power range targets.

Part Context

The LT3825EFE#TRPBF belongs to the LT3825 family of isolated controllers by Analog Devices Inc. It serves as the core control IC for flyback converters, distinct from evaluation boards like DC1143A or demo boards like DC894C-B which utilize this part. The #TRPBF suffix denotes the specific tape-and-reel packaging variant of the standard LT3825EFE controller.
