LT3752HFE-1#PBF

Overview

The LT3752HFE-1#PBF 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 single output configuration. The device features an integrated DC/DC housekeeping controller, eliminating the need for external auxiliary power supplies. It is housed in a 38-pin TSSOP-EP package designed for surface mount installation. The component functions reliably across an extended temperature range from -40°C to +150°C TJ, ensuring stability in demanding industrial environments.

Feature Summary

Optimized for active clamp forward converter topology with integrated housekeeping controller
Supports synchronous rectification for enhanced efficiency
Includes internal soft start and frequency control capabilities

Applications

Industrial power supply systems
Telecommunications equipment
Data center server power modules

Procurement Notes

Verify that the specific suffix #PBF corresponds to the tube packaging variant required for your assembly process. Confirm that the HFE designation aligns with the automotive AEC-Q100 qualification if your application demands this grade. Ensure the 38-TSSOP-EP footprint matches your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when designing active clamp forward converters requiring an integrated housekeeping solution. The internal DC/DC controller simplifies bill of materials by removing auxiliary winding requirements. Consider the 100 kHz to 500 kHz frequency range for balancing size and efficiency. Verify thermal management needs given the +150°C junction temperature rating.

Part Context

This part belongs to the LT3752 series, which includes variants like LT3752EFE-1#PBF and LT3752HFE-1#TRPBF. The series is characterized by its focus on high-efficiency forward conversion architectures. The HFE suffix typically denotes automotive-grade qualification under AEC-Q100 standards, distinguishing it from standard commercial versions.
