It integrates a 750mA switch and synchronous rectifier, which improves efficiency over a diode-based boost topology — particularly at higher output currents. The part is housed in a 6-TDFN exposed-pad package (3x3 mm) and operates over -40°C to +85°C, making it suitable for portable, battery-powered, and industrial equipment where a regulated 3.3V rail must be generated from a single-cell alkaline, Li-ion, or multi-cell battery stack. ## 750mA switch and synchronous rectification The 750mA switch rating is the peak current the internal power FET can handle — it is not the continuous output current. For a 3.3V output from a 1.8V input, expect around 300–400 mA continuous output before the switch current limit is reached, depending on inductor value and efficiency. The synchronous rectifier eliminates the external Schottky diode, saving board space and reducing forward-voltage losses, which matters when every millivolt of headroom counts in a low-input-voltage boost design. ## Active lifecycle, ROHS3, and sourcing posture The MAX8569BETT+T carries an Active product status and is ROHS3 compliant.","metaTitle":"MAX8569BETT+T Boost Converter, 3.3V Fixed Output","metaDescription":"MAX8569BETT+T step-up boost regulator from Analog Devices.

The datasheet application circuit typically specifies a 4.7 µH to 10 µH shielded inductor rated for the peak switch current (750mA). The synchronous rectifier eliminates the need for an external Schottky diode."},{"question":"Is MAX8569BETT+T compatible with 1.8V input?","answer":"Yes. The minimum input voltage is 1.5V, so a 1.8V rail is well within range. The part will boost 1.8V to a regulated 3.3V output. At this input voltage, the available output current will be lower than at higher input voltages due to the switch current limit — expect roughly 300–400 mA continuous output."},{"question":"Is MAX8569BETT+T RoHS compliant?","answer":"Yes, it is ROHS3 compliant, meaning it meets the EU RoHS directive with no exemptions for restricted substances."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX8569BETTT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX8569BETTT when reusing this data.
