LT3752IFE-1

Overview

The LT3752IFE-1#PBF is a switching controller from Analog Devices, designed for forward converter topologies with active clamp and synchronous rectification. 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 supply voltage range of 10.5 V to 16 V and includes an internal house supply. It is housed in a 38-pin TSSOP package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates active clamp and synchronous rectification control for high efficiency
• Supports forward converter topology with programmable伏秒钳位 (volt-second clamp)
• Includes internal house supply regulation to simplify external component count

Applications

• High-efficiency DC-DC power supplies
• Industrial power conversion systems
• Telecommunications equipment power stages

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when ordering. Confirm that the -1 variant input voltage constraints are met by external components as per the datasheet. Ensure the 38-pin TSSOP footprint matches the PCB design. Check current availability status as distribution may vary by region.

Selection Notes

Select this controller for applications requiring forward topology with active clamp benefits. Consider the 100 kHz to 500 kHz frequency range for size-efficiency trade-offs. Verify that the input voltage requirements align with the -1 variant's external component limitations rather than the standard LT3752 range.

Part Context

This component belongs to the LT3752 series of PMIC switching controllers. It is part of Analog Devices' portfolio for managing power conversion tasks. The series is known for integrating complex control loops into a single IC to reduce board space and improve performance in regulated power supplies.

Replacement Considerations

LT3752IFE#PBF is a related variant; verify if the standard input voltage range suffices instead of the -1 specific constraints.
