In a boost converter from 5 V to 12 V, derating for switch losses and inductor ripple, practical output current lands around 400–600 mA. The wide input range from 3 V to 40 V makes it usable on 5 V, 12 V, and 24 V rails — common in automotive and industrial control boards. ## Obsolete — sourcing through independent distribution STMicroelectronics lists the MC34063EBD as Obsolete. For new designs, evaluate the MC34063ABD (same SOIC-8 footprint) as a potential drop-in; verify pin compatibility from the datasheet.","metaTitle":"MC34063EBD STMicroelectronics DC-DC Converter, 33 kHz","metaDescription":"MC34063EBD STMicroelectronics DC-DC converter, 33 kHz switching, 1.5 A switch, 3-40 V input, adjustable output, SOIC-8.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"STMicroelectronics","Series":"-","Package":"Tube","Function":"Step-Up, Step-Down","Topology":"Buck, Boost","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Current - Output":"1.5A (Switch)","Number of Outputs":"1","Base Product Number":"MC34063","Output Configuration":"Positive or Negative","Frequency - Switching":"33kHz","Operating Temperature":"-40°C ~ 125°C (TA)","Synchronous Rectifier":"No","Voltage - Input (Max)":"40V","Voltage - Input (Min)":"3V","Voltage - Output (Max)":"38V","Supplier Device Package":"8-SOIC","Voltage - Output (Min/Fixed)":"1.25V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ded0e68a4eca5ee7ff197c1dcca2753c.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/MC34063EBD","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/MC34063EBD when reusing this data.
