It integrates the switching FET internally. Each channel delivers up to 20.2 mA, dimming via PWM. Supply range is 2.7 V to 5.5 V. Switching at 1 MHz keeps external components small. ## Temperature grade and package — what they mean for the build The LM3699YFQR is rated for -40°C to 125°C junction temperature, which puts it in the industrial-to-automotive range. That covers outdoor telecom, engine-bay-adjacent modules, and factory-floor HMI backlights without a derating step. The package is a 12-bump DSBGA (1.64 mm × 1.24 mm) — a fine-pitch wafer-level chip-scale package. That means the PCB landing pattern is tiny, but assembly requires a solder-paste stencil with good aperture alignment and a reflow profile matched to the lead-free finish. The DSBGA has no leads to inspect visually; X-ray or electrical test verifies the joints. ## Lifecycle and sourcing posture The LM3699YFQR carries an active lifecycle status and is ROHS3 compliant. For BOM planning, that means no LTB risk and no forced redesign horizon. The part is quoted to order — no minimum-buy obligation for engineering samples, and volume pricing scales with quantity.","metaTitle":"LM3699YFQR LED Driver, DC-DC Boost Regulator, 3-Ch, 1 MHz","metaDescription":"LM3699YFQR is a 3-channel DC-DC boost LED driver with PWM dimming, internal switches, 2.7 V to 5.5 V input, 1 MHz switching frequency.","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":"Tape & Reel (TR); Cut Tape (CT)","Topology":"Step-Up (Boost)","Frequency":"1MHz","Applications":"Backlight, Camera Flash","Mounting Type":"Surface Mount","Package / Case":"12-WFBGA, DSBGA","lifecycle_stage":"eol_hot","Number of Outputs":"3","Internal Switch(s)":"Yes","Operating Temperature":"-40°C ~ 125°C (TJ)","Voltage - Supply (Max)":"5.5V","Voltage - Supply (Min)":"2.7V","Supplier Device Package":"12-DSBGA (1.64x1.24)","Current - Output / Channel":"20.2mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.10000","currency":"USD"},{"qty":10,"price":"$0.98200","currency":"USD"},{"qty":25,"price":"$0.93200","currency":"USD"},{"qty":100,"price":"$0.76550","currency":"USD"},{"qty":250,"price":"$0.71560","currency":"USD"},{"qty":500,"price":"$0.63240","currency":"USD"},{"qty":1000,"price":"$0.49926","currency":"USD"},{"qty":3000,"price":"$0.47100","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e5491f591a4dbd98204b7bdaa6f6cc54.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does LM3699YFQR have internal switches?","answer":"Yes, the part includes internal switches, so no external MOSFET is required for the boost converter.
