LT3752EFE-1#PBF

Overview

The LT3752EFE-1#PBF is a current mode PWM controller optimized for active clamp forward converter topologies. It integrates a DC/DC housekeeping controller to simplify system design. The device supports switching frequencies from 100 kHz to 500 kHz and offers a maximum duty cycle of 95%. It operates within a junction temperature range of 0°C to 125°C, with extended specifications available down to -40°C. The component provides one output channel and features a shutdown function. It is housed in a TSSOP-38 package suitable for surface mount applications.

Feature Summary

• Optimized for active clamp forward converter topology with integrated housekeeping controller
• Current mode PWM control architecture for precise regulation
• Adjustable switching frequency range supporting flexible design requirements
• Includes shutdown capability for power management efficiency

Applications

• Active clamp forward power supply designs
• DC/DC housekeeping power circuits
• Industrial power management systems
• Telecommunications equipment power stages

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when sourcing. Confirm that the EFE variant meets the required thermal performance for your application, as specifications are guaranteed from 0°C to 125°C junction temperature. Check for availability restrictions in your region, as some distributors may list limited stock or discontinuation notices. Ensure compatibility with the intended switching frequency range of 100 kHz to 500 kHz during procurement planning.

Selection Notes

Select this component when an active clamp forward topology is required alongside an integrated housekeeping supply. The LT3752EFE-1#PBF is suitable for designs needing current mode control with adjustable frequency up to 500 kHz. Consider the TSSOP-38 package constraints for PCB layout. Verify that the operating temperature range of -40°C to 125°C aligns with environmental conditions. This part is distinct from standard buck controllers due to its specialized forward converter optimization.

Part Context

The LT3752EFE-1#PBF belongs to the LT3752 series by Analog Devices, designed specifically for advanced forward converter applications. It differentiates itself by combining main power control with an internal housekeeping regulator, reducing external component count. The series supports high-efficiency designs through active clamp synchronization. Development kits such as DC1994A and DC1929A are available for evaluation, aiding in the validation of power stage performance before production implementation.

Replacement Considerations

Public confirmed substitute part numbers are not explicitly documented in the provided source material. Consult Analog Devices official documentation for cross-reference lists. Verify pinout and electrical parameter compatibility if considering alternative controllers from other manufacturers.
