It carries an Automotive grade rating and AEC-Q100 qualification, making it suitable for under-hood and chassis-domain power supplies where reliability screening is mandatory. 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.","metaTitle":"LT3752HFE#WPBF Forward Controller, AEC-Q100, 150°C Junction","metaDescription":"LT3752HFE#WPBF active-clamp synchronous forward controller, AEC-Q100 automotive grade, 6.5V–100V supply, 150°C Tj, 38-TSSOP-EP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Grade":"Automotive","Package":"Tube","Function":"Step-Up/Step-Down","Topology":"Forward Converter","Clock Sync":"Yes","Output Type":"Transistor Driver","Mounting Type":"Surface Mount","Output Phases":"1","Qualification":"AEC-Q100","Package / Case":"38-TFSOP (0.173\\\", 4.40mm Width) 31 Leads, Exposed Pad","lifecycle_stage":"eol_hot","Control Features":"Enable, Frequency Control, Soft Start","Duty Cycle (Max)":"95%","Number of Outputs":"1","Output Configuration":"Positive, Isolation Capable","Frequency - Switching":"100kHz ~ 500kHz","Operating Temperature":"-40°C ~ 150°C (TJ)","Synchronous Rectifier":"Yes","Supplier Device Package":"38-TSSOP-EP","Voltage - Supply (Vcc/Vdd)":"6.5V ~ 100V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.63","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.63000","currency":"USD"},{"qty":10,"price":"$9.76600","currency":"USD"},{"qty":50,"price":"$9.36120","currency":"USD"},{"qty":100,"price":"$8.24800","currency":"USD"},{"qty":250,"price":"$7.84316","currency":"USD"},{"qty":500,"price":"$7.33714","currency":"USD"},{"qty":1000,"price":"$6.72993","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/97c3fc57cedd094ee87473634f2876ec.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LT3752HFE#WPBF AEC-Q100 qualified?","answer":"Yes, the LT3752HFE#WPBF is AEC-Q100 qualified and carries an Automotive grade rating."},{"question":"What is the cross reference or equivalent for LT3752HFE#WPBF?","answer":"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."},{"question":"Where can I find the datasheet for LT3752HFE#WPBF?","answer":"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.
