It runs from a 2.9 V to 5.5 V supply rail and switches at 850 kHz, which keeps external flying and reservoir capacitors small enough for space-constrained portable designs. The 20-QFN (3x3 mm) package with exposed pad helps pull heat into the board plane. ## Temperature grade and operating environment Rated for -40°C to 85°C ambient, the LTC3219EUD#PBF covers industrial and outdoor telecom equipment where the enclosure may see freeze-thaw cycles or direct sun. It is not AEC-Q100 qualified, so it does not belong in an automotive ECU or under-hood module without a separate qualification review. For non-automotive applications that stay inside the industrial temperature window, the part is a straightforward fit. ## Lifecycle and sourcing posture The LTC3219EUD#PBF carries an Active product status and is ROHS3 compliant. No end-of-life notice or last-time-buy window has been published.","metaTitle":"LTC3219EUD#PBF LED Driver, 9 Outputs, I2C, 850 kHz, 20-QFN","metaDescription":"LTC3219EUD#PBF is an active, ROHS3-compliant DC DC regulator LED driver with 9 outputs, I2C dimming, 850 kHz switching, 28 mA per channel, and industrial temp","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"DC DC Regulator","Dimming":"I²C","Package":"Tube","Topology":"Switched Capacitor (Charge Pump)","Frequency":"850kHz","Mounting Type":"Surface Mount","Package / Case":"20-WFQFN Exposed Pad","lifecycle_stage":"eol_hot","Number of Outputs":"9","Internal Switch(s)":"Yes","Operating Temperature":"-40°C ~ 85°C (TA)","Voltage - Supply (Max)":"5.5V","Voltage - Supply (Min)":"2.9V","Supplier Device Package":"20-QFN (3x3)","Current - Output / Channel":"28mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.15","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.15000","currency":"USD"},{"qty":10,"price":"$5.52500","currency":"USD"},{"qty":25,"price":"$5.22320","currency":"USD"},{"qty":100,"price":"$4.52670","currency":"USD"},{"qty":250,"price":"$4.29460","currency":"USD"},{"qty":500,"price":"$3.85352","currency":"USD"},{"qty":1000,"price":"$3.28500","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/3219fa.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can LTC3219EUD#PBF drive 9 LEDs with I2C control?","answer":"Yes.
