No factory orders can be placed; the only available stock is from surplus inventory, excess distributor holdings, or broker channels. Every unit we source is physically inspected — date-code consistency, marking laser-etch font, and package integrity checked against known TI production patterns — before it reaches your BOM. ## What the fixed outputs and switching frequency mean for your board The 1.6V and 1.8V outputs are factory-set — there is no external resistor divider to adjust them. This part fits a design that needs exactly those two rails, typically powering a core voltage and an I/O voltage in a portable application. The 2MHz switching frequency pushes the fundamental switching noise above the AM radio band and lets the output filter use a 1µH to 2.2µH inductor and 10µF ceramic output caps. That shrinks the power supply footprint to roughly the size of the IC plus two small passives per channel. The trade-off is slightly higher switching losses than a 500kHz part, but at 600mA load the efficiency advantage of the small solution size usually wins in a battery-powered device.","metaTitle":"TI LM3370SDX-3806/NOPB Dual Buck Regulator, 2MHz, 600mA","metaDescription":"Texas Instruments LM3370SDX-3806/NOPB dual step-down buck regulator, 2.7-5.5V input, fixed 1.6V/1.8V outputs, 600mA per channel, 2MHz switching.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"16-WFDFN Exposed Pad","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Current - Output":"600mA","Number of Outputs":"2","Base Product Number":"LM3370","Output Configuration":"Positive","Frequency - Switching":"2MHz","Operating Temperature":"-30°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"2.7V","Voltage - Output (Max)":"-","Supplier Device Package":"16-WSON (5x4)","Voltage - Output (Min/Fixed)":"1.6V, 1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d36e07764e9d1dcd8a4da3b5c605c8b2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3370SDX-3806%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Is LM3370SDX-3806/NOPB obsolete?","answer":"Yes.
