It accepts 7.5 V to 76 V input and delivers an adjustable output at up to 500 mA. ## 125 kHz switching — what it means for the BOM At 125 kHz, the external inductor and output capacitor will be physically larger than what you'd use with a modern 500 kHz+ switcher. That's the trade-off for the wide input range and the simplicity of a fixed-frequency PWM controller. The 125 kHz rate also keeps switching losses low, which helps at light loads, but the inductor footprint is something to size early in the layout. ## No synchronous rectifier — plan for the external diode Because the MAX5033DASA+T does not integrate a synchronous rectifier, the design needs an external Schottky catch diode. That adds one component and some board area, but it also means the designer can pick a diode with the forward voltage and thermal performance that match the load. At 500 mA output, a 1 A rated Schottky with low Vf is the typical choice. ## Lifecycle and sourcing The part is ROHS3 compliant.","metaTitle":"MAX5033DASA+T Buck Regulator, 500 mA, 76V Input, 8-SOIC","metaDescription":"MAX5033DASA+T is a 500 mA step-down buck regulator from Maxim Integrated. 76V input max, adjustable output, 125 kHz switching, -40°C to 125°C.

Functionally identical — same 500 mA adjustable buck regulator, same 76 V input max, same 125 kHz switching. The \"+T\" suffix indicates the reeled packaging for automated assembly. It is a direct drop-in replacement for the tube-packaged MAX5033DASA."},{"question":"Does MAX5033DASA+T require an external inductor?","answer":"Yes — as a non-synchronous buck regulator switching at 125 kHz, the MAX5033DASA+T requires an external inductor and a Schottky catch diode to form the output stage. The inductor value is selected based on the input voltage, output voltage, and switching frequency per the typical application circuit in the datasheet."},{"question":"Is MAX5033DASA+T suitable for industrial applications?","answer":"Yes. With an operating temperature range of -40°C to 125°C junction temperature and a wide input range up to 76 V, the MAX5033DASA+T is well suited for industrial environments such as factory automation, motor drives, and 24 V or 48 V bus-powered equipment."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX5033DASAT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX5033DASAT when reusing this data.
