LT3752HFE#WTRPBF

Overview

The LT3752HFE#WTRPBF is an active clamp synchronous forward controller from Analog Devices, designed for high-efficiency power conversion. It operates within a supply voltage range of 6.5V to 100V and supports switching frequencies between 100kHz and 500kHz. The device features a maximum duty cycle of 95% and includes clock synchronization capabilities. Packaged in a 38-pin TSSOP with an exposed pad, it is optimized for industrial applications requiring robust performance across temperatures from -40°C to +150°C.

Feature Summary

• Integrates active clamp circuitry to minimize switching losses and improve efficiency in forward converter topologies.
• Supports synchronous rectification for enhanced output regulation and reduced conduction losses.
• Features internal housekeeping regulator to simplify external component requirements.
• Includes clock synchronization input to allow phase alignment in multi-controller systems.

Applications

• Industrial power supplies
• Telecommunications infrastructure
• High-density point-of-load converters

Procurement Notes

Verify the specific suffix 'WTRPBF' against official Analog Devices documentation to confirm tape-and-reel packaging and commercial temperature grade specifications. Ensure compatibility with your PCB footprint for the 38-TFSOP package. Cross-reference part numbers carefully as minor suffix variations may indicate different thermal grades or packaging formats.

Selection Notes

Select this controller for forward converter designs requiring high input voltages up to 100V. Consider its wide operating temperature range for harsh environments. Evaluate the need for clock synchronization if multiple phases are used. Compare against standard PWM controllers to assess the efficiency gains provided by the integrated active clamp and synchronous rectification features.
