LT3752EFE

Overview

The LT3752EFE 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, eliminating the need for auxiliary windings. The device supports switching frequencies from 100 kHz to 500 kHz and offers a maximum duty cycle of 95%. It operates within an extended temperature range of -40°C to +125°C and features a shutdown function. Packaged in a 38-TSSOP-EP format, it draws 7.5 mA of working supply current.

Feature Summary

Integrates a dedicated DC/DC housekeeping controller for internal power management
Optimized for active clamp forward converter topology with synchronous rectification control
Supports programmable switching frequency ranging from 100 kHz to 500 kHz
Includes a shutdown pin for system power management

Applications

Active clamp forward power supplies
Isolated DC/DC conversion systems
Industrial power management modules

Procurement Notes

Verify the specific suffix (e.g., EFE vs EFEB) against the required package type and tape/reel configuration. Confirm that the selected variant matches the intended thermal performance and PCB footprint requirements. Ensure compatibility with the target switching frequency range and input voltage specifications before finalizing procurement orders.

Selection Notes

Select this component when designing isolated power stages requiring integrated housekeeping regulation. It is suitable for applications demanding high efficiency through active clamp techniques. Consider the 38-pin TSSOP package for thermal dissipation needs. Validate that the current mode control architecture aligns with the transient response requirements of the load.

Part Context

This part belongs to the LT3752 family of switching controllers designed for forward converters. It distinguishes itself by embedding a housekeeping regulator, simplifying transformer design. The series targets high-reliability industrial and commercial power applications where component count reduction is critical.
