The 2.2MHz switching frequency lets you use small 0603 or 0805 inductors and ceramic output capacitors, keeping the total solution area tight for space-constrained point-of-load rails. ## Input and output voltage boundaries Input range spans 2.5V minimum to 5.5V maximum — covers 3.3V and 5V intermediate buses, single-cell Li-ion, and 5V USB rails. The adjustable output goes from a 0.6V reference up to 4V, so it can feed 1.2V core, 1.8V I/O, 2.5V analog, or 3.3V peripheral rails from the same BOM entry. ## Thermal range and package reality The 6-VSON-HR package (1.5x1.5 mm body) with an exposed thermal pad requires a solid copper pour on the top layer and at least two thermal vias to keep the junction below 125°C at full 4A load — the datasheet layout example is worth following closely. ## Synchronous rectification and efficiency The 4A continuous output is real — the package thermal performance, not the silicon, sets the practical limit in a 25°C ambient with minimal airflow.","metaTitle":"TPS62827DMQT 4A Step-Down Buck Converter, 2.2MHz, 6-VSON-HR","metaDescription":"Texas Instruments TPS62827DMQT 4A adjustable step-down buck converter, 2.5V–5.5V input, 2.2MHz switching, -40°C to 125°C TJ, 6-VSON-HR package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"6-VFDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"4A","Number of Outputs":"1","Base Product Number":"TPS62827","Output Configuration":"Positive","Frequency - Switching":"2.2MHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"2.5V","Voltage - Output (Max)":"4V","Supplier Device Package":"6-VSON-HR (1.5x1.5)","Voltage - Output (Min/Fixed)":"0.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ef62a7309013253e63199e32cc809f43.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62827DMQT/alternatives.json"},"ai":{"faq":[{"question":"What is the output current of TPS62827DMQT?","answer":"The TPS62827DMQT delivers 4A continuous output current.
