Supporting buck, boost, and inverting topologies with a 1.5A internal switch and 3-40V input range, it provides versatile power conversion with minimal external components.","working_principle":"The MC34063A uses an oscillator to generate switching pulses that drive the internal Darlington switch transistor. The comparator compares the output voltage (via a divider) with the 1.25V reference, controlling the switch duty cycle. An external current-sense resistor provides over-current protection. The oscillator frequency is set by an external timing capacitor. The device supports continuous and discontinuous conduction modes.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>Switch Collector<\/td><td>Darlington switch collector<\/td><\/tr><tr><td>2<\/td><td>Switch Emitter<\/td><td>Darlington switch emitter<\/td><\/tr><tr><td>3<\/td><td>Timing Capacitor<\/td><td>Oscillator frequency set<\/td><\/tr><tr><td>4<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>5<\/td><td>Comparator Inverting Input<\/td><td>Voltage feedback<\/td><\/tr><tr><td>6<\/td><td>VCC<\/td><td>Power supply (3-40V)<\/td><\/tr><tr><td>7<\/td><td>Ipeak Sense<\/td><td>Current limit sense<\/td><\/tr><tr><td>8<\/td><td>Driver Collector<\/td><td>Driver transistor collector<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Battery DC-DC converters<\/li><li>Automotive power regulation<\/li><li>LED driver supplies<\/li><li>Voltage inverting circuits<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Notes<\/th><\/tr><tr><td>onsemi<\/td><td>MC33063ADR<\/td><td>Industrial temp version<\/td><\/tr><tr><td>TI<\/td><td>MC34063ADR2G<\/td><td>Pin-compatible<\/td><\/tr><tr><td>ST<\/td><td>MC34063A<\/td><td>Pin-compatible<\/td><\/tr><tr><td>onsemi<\/td><td>NCP3063<\/td><td>Improved version, 1.5A<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/11044","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/comments?post=11044"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/11044\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/media\/11107"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/media?parent=11044"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/categories?post=11044"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/tags?post=11044"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/chip_brand?post=11044"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
