LT3752IFE-1#TRPBF

Overview

The LT3752IFE-1#TRPBF is a current mode PWM controller optimized for active clamp forward converter topologies, manufactured by Analog Devices Inc. It operates within a switching frequency range of 100 kHz to 500 kHz and supports a maximum duty cycle of 95%. The device features an integrated DC/DC housekeeping controller and is housed in a 38-TSSOP-EP package. It functions with a supply voltage of up to 10 V and draws 10 mA output current. The component operates reliably between -40°C and +125°C.

Feature Summary

• Optimized for active clamp forward converter topology
• Includes integrated DC/DC housekeeping controller
• Supports clock synchronization capabilities

Applications

• Active clamp forward power supplies
• Isolated DC/DC conversion systems
• Industrial power management modules

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing from distributors. Confirm that the part number matches the exact Analog Devices specification sheet for the LT3752-1 variant. Ensure compatibility with the required thermal performance for the TSSOP-38 package. Cross-reference the manufacturer's latest documentation to confirm RoHS compliance status and any recent product change notifications affecting this specific revision.

Selection Notes

Select this component when designing isolated power supplies requiring an active clamp forward topology. The integrated housekeeping controller simplifies bias winding requirements compared to standard controllers. Consider the 38-pin TSSOP-EP package for thermal dissipation needs. Verify that the 100 kHz to 500 kHz frequency range aligns with the desired transformer size and efficiency targets for the application.

Part Context

This part belongs to the LT3752 family of switching controllers designed for high-efficiency isolated applications. It differs from non-integrated variants by including the housekeeping regulator circuitry on-chip. The #TRPBF suffix denotes the specific reel packaging format for automated assembly processes, distinguishing it from tube-packaged equivalents like the #PBF version.
