Its 200kHz to 580kHz switching range lets the designer trade transformer size against switching losses — higher frequency shrinks the magnetics but pushes gate-drive losses. Two transistor-driver outputs with an 80% maximum duty cycle are configured for active-clamp reset, which recovers transformer core energy and improves efficiency over a conventional RCD clamp. The controller integrates dead-time control, frequency control, ramp compensation, and a soft-start pin. Clock synchronization is on-board — multiple LM5025 units can be interleaved to reduce input/output ripple, or the controller can lock to an external clock for system-level noise management. ## Supply rails and temperature grade Bias supply range is 8V to 15V, typical for a telecom or industrial backplane rail. Packaged in a 16-TSSOP with 4.40mm body width, the footprint is compact enough for a 2-layer board if the thermal pad is stitched to a ground plane. No synchronous rectifier output is integrated — the external SR FET must be driven from the secondary side or from an auxiliary winding. ## Lifecycle and compliance The tube packaging is the standard delivery form for this variant. If reel-fed assembly is preferred, check the LM5025MTCX/NOPB tape-and-reel sibling.","metaTitle":"Texas Instruments LM5025MTC/NOPB Forward Converter","metaDescription":"Texas Instruments LM5025MTC/NOPB active forward converter controller, 8-15V supply, 80% duty cycle, 200-580kHz switching, -40 to 125°C, 16-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Function":"Step-Up/Step-Down","Topology":"Forward Converter","Clock Sync":"Yes","Output Type":"Transistor Driver","Mounting Type":"Surface Mount","Output Phases":"1","Package / Case":"16-TSSOP (0.173\\\", 4.40mm Width)","lifecycle_stage":"eol_hot","Control Features":"Dead Time Control, Frequency Control, Ramp, Soft Start","Duty Cycle (Max)":"80%","Number of Outputs":"2","Output Configuration":"Positive, Isolation Capable","Frequency - Switching":"200kHz ~ 580kHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"No","Supplier Device Package":"16-TSSOP","Voltage - Supply (Vcc/Vdd)":"8V ~ 15V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.37","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.37000","currency":"USD"},{"qty":10,"price":"$3.02200","currency":"USD"},{"qty":25,"price":"$2.85720","currency":"USD"},{"qty":100,"price":"$2.47630","currency":"USD"},{"qty":250,"price":"$2.34928","currency":"USD"},{"qty":500,"price":"$2.10800","currency":"USD"},{"qty":1000,"price":"$1.79700","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a307f36789e945defd064de94f04a292.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second-source for LM5025MTC/NOPB?","answer":"The UCC2806DWTR is a peer PWM controller but it targets boost, flyback, and forward topologies with a 47kHz switching frequency and a 50% max duty cycle — significantly lower than the LM5025's 200-580kHz range.
