PWM dimming is supported directly, making it suitable for automotive exterior lighting, industrial high-bay fixtures, and architectural LED strings where the bus voltage can run up to 75V. ## What the 75V input and 1.5A output mean for the BOM A 75V maximum input voltage is the headline rating on this part. It means the LM3406HVMH/NOPB can be fed directly from a 48V nominal industrial rail or an automotive 24V battery bus (including load-dump transients) without an external pre-regulator. The 1.5A continuous output current drives a single high-power LED or a series string of lower-current LEDs, depending on the forward voltage stack. The LM3406HVMH/NOPB is active and ROHS3 compliant. No AEC-Q grade is listed.","metaTitle":"LM3406HVMH/NOPB LED Driver, Buck, 75V, 1.5A, PWM Dimming","metaDescription":"Texas Instruments LM3406HVMH/NOPB DC-DC regulator, step-down (buck) LED driver with PWM dimming. 75V max input, 1.5A output, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"DC DC Regulator","Dimming":"PWM","Package":"Tube","Topology":"Step-Down (Buck)","Frequency":"10kHz ~ 1MHz","Applications":"Automotive, Lighting","Mounting Type":"Surface Mount","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width) Exposed Pad","lifecycle_stage":"eol_hot","Number of Outputs":"1","Internal Switch(s)":"Yes","Operating Temperature":"-40°C ~ 125°C (TJ)","Voltage - Supply (Max)":"75V","Voltage - Supply (Min)":"6V","Supplier Device Package":"14-HTSSOP","Current - Output / Channel":"1.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.87","priceTiers":[{"qty":1,"price":"$3.87000","currency":"USD"},{"qty":10,"price":"$3.47600","currency":"USD"},{"qty":25,"price":"$3.28640","currency":"USD"},{"qty":100,"price":"$2.84830","currency":"USD"},{"qty":250,"price":"$2.70224","currency":"USD"},{"qty":500,"price":"$2.42472","currency":"USD"},{"qty":1000,"price":"$2.06700","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3615cfc849103e42bb875a9524a259f6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3406HVMH%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Does LM3406HVMH/NOPB support PWM dimming for automotive lighting?","answer":"Yes, PWM dimming is listed as a key feature, and the part is rated for the -40°C to 125°C junction temperature range typical of automotive under-hood environments.
