The 1.5A integrated switch sets the output current ceiling; for loads above that you add an external pass transistor. ## Input voltage range and output adjustability Input range spans 3 V to 40 V, which covers unregulated wall warts, 12 V automotive rails, and 24 V industrial supplies. Output is adjustable from a 1.25 V reference up to 40 V — the feedback divider sets the regulation point. ## 100 kHz switching — thermal and layout trade-offs Fixed 100 kHz oscillator keeps the inductor and capacitor sizes moderate but limits the bandwidth for fast transient response. At this frequency the switching losses are low enough that the 8-DIP package can dissipate the heat without a heatsink in most designs up to the 1.5 A switch rating. This is a commercial-grade part; do not plan for outdoor telecom cabinets, engine bays, or freezer environments. For extended temperature, look at the MC34063A industrial-grade variants in the same family. Product status is Active.","metaTitle":"MC34063APE4 DC-DC Switching Regulator, Step-Up/Down, 1.5A","metaDescription":"Texas Instruments MC34063APE4 DC-DC converter, step-up/step-down, 1.5A switch, 3-40V input, 100kHz, 8-DIP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tube","Function":"Step-Up, Step-Down","Topology":"Buck, Boost","Output Type":"Adjustable","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Current - Output":"1.5A (Switch)","Number of Outputs":"1","Base Product Number":"MC34063","Output Configuration":"Positive or Negative","Frequency - Switching":"100kHz","Operating Temperature":"0°C~70°C(TA)","Synchronous Rectifier":"No","Voltage - Input (Max)":"40V","Voltage - Input (Min)":"3V","Voltage - Output (Max)":"40V (Switch)","Supplier Device Package":"8-PDIP","Voltage - Output (Min/Fixed)":"1.25V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4e044b587f1f11d06da1dc60b5c13058.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MC34063APE4/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MC34063APE4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MC34063APE4 when reusing this data.
