It delivers a single adjustable output up to ±28 V from an input of 2.7 V to 5.5 V, with a 500 mA switch current limit. The 300 kHz switching frequency keeps external inductor and capacitor sizes moderate for board-space-constrained designs. No synchronous rectifier is used, so the external diode selection matters for efficiency at higher output currents. Typical applications include LCD bias supplies, battery-powered equipment, and multi-output rails where a single inductor or coupled-winding transformer generates a positive or negative voltage. ## Output voltage range and topology flexibility The output is adjustable from ±0.8 V up to ±28 V, covering both positive and negative rail generation from a single IC. The SEPIC topology is particularly useful when the output voltage can be above, below, or equal to the input — a common requirement in battery-powered systems where the cell voltage drops below the regulated rail. Flyback mode adds isolation with a coupled inductor, though the IC itself does not provide isolation; the transformer turns ratio and feedback network set the output. This flexibility means one BOM line can serve multiple designs by changing only the external passives and transformer. ## Package and mounting Surface-mount 8-SOIC package (0.154\" body width, 3.90 mm). The supplier device package is also 8-SOIC. Standard SOIC-8 footprint; no thermal pad — junction-to-ambient thermal performance depends on copper area on the PCB. For 500 mA switch current in boost or SEPIC mode, ensure adequate ground-plane copper for heat spreading.","metaTitle":"MAX629ESA+T IC Regulator Boost/Flyback/SEPIC, 8-SOIC, Active","metaDescription":"MAX629ESA+T from Analog Devices is an adjustable-output switching regulator supporting boost, flyback, and SEPIC topologies.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Up, Step-Up/Step-Down","Topology":"Boost, Flyback, SEPIC","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Output":"500mA","Number of Outputs":"1","Output Configuration":"Positive or Negative","Frequency - Switching":"300kHz","Operating Temperature":"-40°C ~ 85°C (TA)","Synchronous Rectifier":"No","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"2.7V","Voltage - Output (Max)":"±28V","Supplier Device Package":"8-SOIC","Voltage - Output (Min/Fixed)":"±0.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.62176","stockQuantity":0,"priceTiers":[{"qty":2500,"price":"$4.62176","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX629.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can I use MAX629ESA+T for a SEPIC application?","answer":"Yes, SEPIC is one of the supported topologies.
