LT3752HFE-1

Overview

The LT3752HFE-1#PBF is a current mode PWM controller optimized for active clamp forward converter topologies. It integrates a DC/DC housekeeping controller to manage internal power requirements. The device operates in a 38-lead TSSOP-EP package, providing isolation-capable output step-up and step-down regulation capabilities. This component serves as a forward converter regulator designed for high-efficiency power conversion applications requiring precise current mode control.

Feature Summary

Optimized for active clamp forward converter topology
Integrates DC/DC housekeeping controller
Current mode PWM control architecture

Applications

Active clamp forward power supplies
Isolated DC/DC conversion systems
Housekeeping power management circuits

Procurement Notes

Verify the specific suffix #PBF indicates a leaded package variant when sourcing. Confirm that the HFE designation corresponds to the correct temperature grade and package type required for your design. Check manufacturer documentation for RoHS compliance status and any regional shipping restrictions that may apply to this specific part number before placing orders.

Selection Notes

Select this controller when an active clamp forward topology is required for efficient power conversion. Ensure the design supports current mode PWM control and utilizes the integrated housekeeping function. Verify compatibility with the 38-lead TSSOP-EP package constraints and thermal requirements. Confirm that the application benefits from the isolated output step-up or step-down capabilities inherent to this regulator.
