LT3752MPFE-1#PBF

Overview

The LT3752MPFE-1#PBF is a switching controller manufactured by Analog Devices, designed for active clamp synchronous forward converters. It operates within a switching frequency range of 100 kHz to 500 kHz and supports a maximum duty cycle of 95%. The device features a single output configuration with an internal house supply capability. It is housed in a 38-pin TSSOP package with an exposed pad, suitable for surface mount installation. The component is tested and guaranteed to function across a junction temperature range from -55°C to +150°C.

Feature Summary

• Supports active clamp synchronous forward topology with integrated house supply management
• Operates at adjustable switching frequencies between 100 kHz and 500 kHz
• Guaranteed performance over extended industrial temperature ranges up to 150°C junction temperature

Applications

• Active clamp synchronous forward converter designs
• Industrial power supply systems requiring wide temperature operation
• High-efficiency DC-DC conversion applications utilizing forward topology

Procurement Notes

Verify the specific suffix MPFE-1 against official Analog Devices documentation to confirm pinout and electrical characteristics match your design requirements. Confirm RoHS compliance status through current datasheets as specifications may evolve. Ensure the 38-pin TSSOP package dimensions align with your PCB footprint constraints before finalizing procurement decisions.

Selection Notes

Select this component when designing forward converters that require active clamp synchronization and internal house supply regulation. Consider the 38-pin TSSOP package size and the -55°C to +150°C operating range for harsh environment applications. Evaluate the 100 kHz to 500 kHz frequency range against magnetic component selection needs.

Part Context

This part belongs to the LT3752 series of switching controllers from Analog Devices. It is specifically engineered for forward converter topologies, distinguishing it from buck or boost controllers in the same family. The MPFE-1 designation indicates a specific package and temperature grade variant within the broader LT3752 product line.

Replacement Considerations

Consult official Analog Devices substitution guides for verified equivalents. Generic forward controllers may lack the specific active clamp synchronization and internal house supply features required for direct replacement without circuit redesign.
