It integrates a synchronous rectifier, so no external Schottky catch diode is needed. The fixed 550 kHz switching frequency sets the inductor value and EMI profile. Output current is rated at 1.2 A continuous, and the input range spans 2.65 V to 10 V. ## Package and temperature grade Housed in a 16-lead SSOP (0.154\" body width, 3.90 mm), this is a surface-mount part intended for reflow assembly. The operating temperature range is -40°C to 85°C. ## Sourcing and lifecycle The LTC1879EGN#PBF carries an active lifecycle status and is RoHS3 compliant.","metaTitle":"LTC1879EGN#PBF Buck Regulator, 1.2 A, 550 kHz, 16-SSOP","metaDescription":"LTC1879EGN#PBF is an active step-down buck regulator from Analog Devices.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"16-SSOP (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Output":"1.2A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"550kHz","Operating Temperature":"-40°C ~ 85°C (TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"10V","Voltage - Input (Min)":"2.65V","Voltage - Output (Max)":"10V","Supplier Device Package":"16-SSOP","Voltage - Output (Min/Fixed)":"0.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.36","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.36000","currency":"USD"},{"qty":10,"price":"$9.35900","currency":"USD"},{"qty":25,"price":"$8.92400","currency":"USD"},{"qty":100,"price":"$7.74850","currency":"USD"},{"qty":250,"price":"$7.40028","currency":"USD"},{"qty":500,"price":"$6.74730","currency":"USD"},{"qty":1000,"price":"$5.87668","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7717533372a43bc863b6b49d21c88790.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between LTC1879EGN#PBF and LTC1879EGN#TRPBF?","answer":"The two order codes share identical silicon and package. The difference is the shipping medium: LTC1879EGN#PBF ships in a tube, while the TRPBF suffix indicates tape-and-reel packaging. For high-volume pick-and-place, the TR version is the usual choice; for prototype or low-volume builds, the tube version is fine."},{"question":"Does LTC1879EGN#PBF require an external Schottky diode?","answer":"No. The LTC1879EGN#PBF integrates a synchronous rectifier, so it does not need an external catch diode.
