It integrates the switching FET internally. Each channel delivers up to 20.2 mA, dimming via PWM. Switching at 1 MHz keeps external components small. 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. For BOM planning, that means no LTB risk and no forced redesign horizon.","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":["DC-DC Power Modules"],"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","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,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3699YFQR/alternatives.json"},"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.
