LT3752HFE#TRPBF

Overview

The LT3752HFE#TRPBF is a switching controller designed for active clamp synchronous forward converters. It operates within a wide input voltage range and supports isolation-capable outputs. The device features a fixed switching frequency range of 100 kHz to 500 kHz and includes an internal housekeeping supply. It is housed in a 38-lead TSSOP package with exposed pad, suitable for surface mount installation across temperatures from -40°C to +150°C.

Feature Summary

• Supports active clamp synchronous forward topology
• Includes internal housekeeping supply for simplified design
• Capable of driving high-side N-channel MOSFETs without external drivers
• Features cycle-by-cycle current mode control

Applications

• Telecommunications power supplies
• Industrial point-of-load converters
• Server and data center power distribution
• High-density DC-DC conversion systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm that the H variant meets the required thermal performance for your application. Check Analog Devices documentation for any product change notifications affecting pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component for applications requiring isolated forward converter topologies with high efficiency. Ensure the input voltage range aligns with the system requirements. Consider the thermal dissipation capabilities of the TSSOP-38 package. Verify compatibility with external MOSFETs for the intended power level.

Part Context

This part belongs to the LT3752 series of controllers. It is distinct from LED driver variants like the LT3755. The family focuses on forward and flyback architectures. The HFE designation specifies the package type and temperature grade.

Replacement Considerations

LT3752HFE-1#TRPBF is a functional equivalent within the same series.
