The 250 kHz switching frequency keeps the external flying capacitors small enough for a compact PCB layout. ## Output configuration and load budget The single-output ratiometric topology can be wired as a positive doubler, an inverter, or a split-rail divider — no inductor needed. The 60 mA rating is continuous; at elevated ambient the SOT-23-5's junction-to-ambient thermal resistance will limit usable current, so budget derating above 85°C case temperature. The synchronous rectifier is disabled internally, so the output is unregulated and tracks the input ratio.","metaTitle":"TPS60403QDBVRQ1 Automotive Charge Pump, 60 mA, SOT-23-5","metaDescription":"Texas Instruments TPS60403QDBVRQ1, AEC-Q100 qualified, 250 kHz switched-capacitor charge pump. 60 mA output, inverting or doubling, SOT-23-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Ratiometric","Topology":"Charge Pump","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"60mA","Number of Outputs":"1","Base Product Number":"TPS60403","Output Configuration":"Positive or Negative","Frequency - Switching":"250kHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"No","Voltage - Input (Max)":"5.25V","Voltage - Input (Min)":"1.8V","Voltage - Output (Max)":"-","Supplier Device Package":"SOT-23-5","Voltage - Output (Min/Fixed)":"-Vin, 2Vin, Vin/2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0fcce43ca11bb9bf9ff011f6ba508f4c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS60403QDBVRQ1/alternatives.json"},"ai":{"faq":[{"question":"Can TPS60403QDBVRQ1 generate a negative voltage?","answer":"Yes — the output configuration supports positive or negative output.
