Technical Details & Description

Automotive-grade active-clamp forward controller

The LT3752HFE#WPBF from Analog Devices is an active-clamp synchronous forward controller designed for step-up/step-down isolated power conversion in automotive and industrial environments. The controller operates from a 6.5V to 100V supply rail, so it can connect directly to a 12V, 24V, or 48V automotive bus without an intermediate regulator, and its 150°C junction temperature rating supports operation in high-ambient locations like the engine bay or transmission tunnel.

Package and thermal layout

The 38-lead TSSOP-EP (exposed pad) package is the only package option. The controller's 100kHz–500kHz switching range and 95% duty cycle mean the transformer and output stage can be sized for a given power level, but the thermal pad is the bottleneck — without proper via stitching, the part will thermally limit before the electrical ratings are reached.

Frequently asked questions

Is LT3752HFE#WPBF AEC-Q100 qualified?

Yes, the LT3752HFE#WPBF is AEC-Q100 qualified and carries an Automotive grade rating.

What is the cross reference or equivalent for LT3752HFE#WPBF?

The closest functional equivalent is the LT3752HFE#PBF. It shares the same active-clamp synchronous forward controller design, same 6.5V–100V supply range, same 150°C junction rating, same AEC-Q100 qualification, and same 38-TSSOP-EP package. The #WPBF suffix indicates a different packing configuration (tube vs. reel), not a silicon change. For a second-source option with slightly different control features, the LT3753HFE#PBF is also pin-compatible but has a narrower 8.5V minimum supply and omits the Enable pin.

Where can I find the datasheet for LT3752HFE#WPBF?

The datasheet is available from Analog Devices under the base part number LT3752. The LT3752HFE#WPBF is a specific ordering option (automotive-grade, 38-lead TSSOP-EP, tube). The datasheet covers the full family including the LT3752, LT3752-1, and the H-grade and MP-grade temperature variants. The switching frequency range, active-clamp timing equations, and transformer design guidelines are all in that document.
