It operates from a supply voltage (Vcc/Vdd) range of 2V to 10V and delivers a single positive output with a transistor driver output type. Key control features include enable and soft start, and the device supports clock synchronization for noise-sensitive multi-rail systems. The maximum duty cycle is 100%, allowing dropout-free operation near the input rail. The part is housed in an 8-SOIC package (0.154\", 3.90mm width) with surface-mount mounting. The commercial temperature grade of 0°C to 70°C suits indoor power supplies, telecom line cards, and office equipment where ambient conditions are controlled. ## Sourcing and Lifecycle Status It is ROHS3 compliant, so no exemption issues for global BOMs. No stock-holding claim is made here; we source per RFQ from authorized and vetted supply chains. ## Key Parametric Decisions for the BOM The 2V to 10V supply range means this controller can be biased from a 3.3V or 5V rail without an extra regulator. The 100% duty cycle capability is useful when the output must track the input closely, such as in battery-powered systems near end-of-discharge. Clock synchronization (Clock Sync: Yes) allows the switching frequency to be locked to an external clock, reducing beat-frequency noise in multi-phase or multi-rail designs. The absence of synchronous rectification (Synchronous Rectifier: No) means an external Schottky diode is needed for the low-side path, adding a component but keeping the controller simple and cost-effective.","metaTitle":"LTC1622CS8#PBF Buck Controller – Active, 8-SOIC","metaDescription":"LTC1622CS8#PBF by Analog Devices – Step-down (buck) switching regulator controller, 8-SOIC package, 2V-10V Vcc, 100% duty cycle, clock sync, enable, soft start.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Package":"Tube","Function":"Step-Down","Topology":"Buck","Clock Sync":"Yes","Output Type":"Transistor Driver","Mounting Type":"Surface Mount","Output Phases":"1","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Control Features":"Enable, Soft Start","Duty Cycle (Max)":"100%","Number of Outputs":"1","Output Configuration":"Positive","Operating Temperature":"0°C ~ 70°C (TA)","Synchronous Rectifier":"No","Supplier Device Package":"8-SO","Voltage - Supply (Vcc/Vdd)":"2V ~ 10V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.49","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.49000","currency":"USD"},{"qty":10,"price":"$5.86300","currency":"USD"},{"qty":25,"price":"$5.59040","currency":"USD"},{"qty":100,"price":"$4.85410","currency":"USD"},{"qty":300,"price":"$4.63590","currency":"USD"},{"qty":500,"price":"$4.22684","currency":"USD"},{"qty":1000,"price":"$3.68145","currency":"USD"},{"qty":2500,"price":"$3.54510","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/1622fs.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second-source for LTC1622CS8#PBF?","answer":"The LTC1771ES8#TRPBF is a close functional peer: it is also a buck controller in an 8-SOIC package with 100% duty cycle and enable/soft start.
