Under light-load conditions, the controller automatically switches to PFM (Pulse Frequency Modulation) mode, skipping pulses to reduce switching losses and maintain high efficiency. The BS (boost) pin uses an external bootstrap capacitor to drive the high-side MOSFET gate above VIN. During output short circuit, the switching frequency folds back from 550kHz to 140kHz to reduce power dissipation.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>BS<\/td><td>Bootstrap for high-side gate driver (connect 0.1uF cap to SW)<\/td><\/tr><tr><td>2<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>3<\/td><td>FB<\/td><td>Feedback input (0.8V reference)<\/td><\/tr><tr><td>4<\/td><td>EN<\/td><td>Enable (high=on, low=shutdown, float or 1M to VIN for always-on)<\/td><\/tr><tr><td>5<\/td><td>IN<\/td><td>Input voltage (4.75-40V)<\/td><\/tr><tr><td>6<\/td><td>SW<\/td><td>Power switch output (connect to inductor and diode)<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Battery-powered devices<\/li><li>Industrial power supplies<\/li><li>Portable media devices<\/li><li>Automotive accessory power<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Spec<\/th><th>Package<\/th><\/tr><tr><td>MP1484EN<\/td><td>MPS<\/td><td>4.75-18V 2A buck<\/td><td>SOIC-8<\/td><\/tr><tr><td>SY8120BABC<\/td><td>Silergy<\/td><td>4.5-18V 5A sync buck<\/td><td>SOT23-6<\/td><\/tr><tr><td>XL1509-5.0E1<\/td><td>XLSEMI<\/td><td>4.5-40V 2A buck<\/td><td>SOIC-8<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9826","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=9826"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9826\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=9826"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=9826"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=9826"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=9826"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
