An internal power PMOS switch connects the input to the SW pin, energizing the external inductor. When the switch opens, current flows through the external Schottky diode. The FB pin senses the output voltage through a resistor divider and compares it to the 1.25V reference. The error amplifier adjusts the PWM duty cycle to maintain regulation. During output short circuit, the switching frequency folds back from 180kHz to 48kHz to reduce power dissipation.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>2<\/td><td>FB<\/td><td>Feedback input (1.25V reference)<\/td><\/tr><tr><td>3<\/td><td>SW<\/td><td>Power switch output<\/td><\/tr><tr><td>4<\/td><td>VC<\/td><td>Internal regulator bypass (1uF cap to VIN)<\/td><\/tr><tr><td>5<\/td><td>VIN<\/td><td>Input voltage (8-36V)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>LCD monitors and TVs<\/li><li>Portable instrument power supplies<\/li><li>Telecom and networking equipment<\/li><li>Battery chargers<\/li><li>Automotive power systems<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Spec<\/th><th>Package<\/th><\/tr><tr><td>LM2596T-5.0<\/td><td>TI<\/td><td>3A 40V buck<\/td><td>TO263-5<\/td><\/tr><tr><td>MP8759GD-Z<\/td><td>MPS<\/td><td>5A 18V sync buck<\/td><td>QFN-12<\/td><\/tr><tr><td>SY8120BABC<\/td><td>Silergy<\/td><td>5A 18V sync buck<\/td><td>SOT23-6<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/9799","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=9799"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/9799\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=9799"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=9799"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=9799"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=9799"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
