It accepts an input from 0.8 V minimum up to 5.5 V maximum and delivers an adjustable output from 2 V up to 5.5 V, with a 400 mA switch current limit. The 0.8 V minimum input means it can start from a single alkaline cell or a Li-ion battery near its end-of-discharge voltage, making it a candidate for portable and battery-backed applications where the rail must stay alive as the cell sags. The synchronous rectifier replaces the usual external Schottky catch diode with an internal low-Rds(on) FET, which improves efficiency at moderate output currents and simplifies the BOM by one component — the inductor and two ceramic caps are the only external parts needed for a basic boost. ## Input and output voltage boundaries for the BOM The 5.5 V output ceiling matches the input maximum, so this is a low-to-medium voltage boost — not for 12 V or 24 V rails. The 400 mA switch current rating is the peak current the internal FET can handle cycle-by-cycle. In a boost converter, the input current is higher than the output current by the ratio Vout/Vin times efficiency — so at a 3.3 V output from a 1.5 V input, the input current can approach 1 A even though the output load is only a few hundred milliamps. The inductor saturation current and the switch current limit together set the real output capability. ## Package, footprint, and supply format Housed in a 5-pin TSOT-23-5 — a thin version of the standard SOT-23-5 with a lower profile (~1.0 mm seated height). The footprint is the same as a standard SOT-23-5, so existing land patterns for that package work without modification. The TR format is the volume-production reel; CT is for prototype or small-batch builds. Both are surface-mount reflow compatible. ## Active lifecycle and compliance standing This satisfies EU RoHS requirements for equipment placed on the market after 2015.","metaTitle":"MAX1723EZK+T Analog Devices Boost Converter, 400mA","metaDescription":"Analog Devices MAX1723EZK+T step-up DC-DC converter, 0.8V to 5.5V input, adjustable output to 5.5V, 400mA switch, synchronous rectifier, TSOT-23-5, active","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Up","Topology":"Boost","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"SOT-23-5 Thin, TSOT-23-5","lifecycle_stage":"eol_hot","Current - Output":"400mA (Switch)","Number of Outputs":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 85°C (TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"0.8V","Voltage - Output (Max)":"5.5V","Supplier Device Package":"TSOT-23-5","Voltage - Output (Min/Fixed)":"2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.39","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.39000","currency":"USD"},{"qty":10,"price":"$3.94200","currency":"USD"},{"qty":25,"price":"$3.72680","currency":"USD"},{"qty":100,"price":"$3.23000","currency":"USD"},{"qty":250,"price":"$3.06432","currency":"USD"},{"qty":500,"price":"$2.74962","currency":"USD"},{"qty":1000,"price":"$2.31896","currency":"USD"},{"qty":2500,"price":"$2.20301","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What package does MAX1723EZK+T come in?","answer":"It is supplied in a 5-pin TSOT-23-5 package, which is a thin variant of the SOT-23-5.
