The high-side MOSFET switches on to energize the inductor, then switches off while the low-side synchronous MOSFET provides the inductor current return path, eliminating the need for an external Schottky diode. Current-mode control provides tight load transient response and cycle-by-cycle current limit. At light loads, the regulator operates in low-frequency mode to maintain high efficiency.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>EN<\/td><td>Enable input (active high)<\/td><\/tr><tr><td>2<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>3<\/td><td>SW<\/td><td>Switch node (inductor connection)<\/td><\/tr><tr><td>4<\/td><td>VIN<\/td><td>Input power supply (4.6-18V)<\/td><\/tr><tr><td>5<\/td><td>FB<\/td><td>Feedback voltage input<\/td><\/tr><tr><td>6<\/td><td>BS<\/td><td>Bootstrap for high-side gate drive<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Networking systems point-of-load<\/li><li>FPGA\/DSP\/ASIC core power<\/li><li>Notebook computer power<\/li><li>Distributed power systems<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Spec1<\/th><th>Spec2<\/th><\/tr><tr><td>SY8120B<\/td><td>Silergy<\/td><td>18V\/2A sync buck<\/td><td>SOT23-6<\/td><\/tr><tr><td>MP1484<\/td><td>MPS<\/td><td>18V\/2A sync buck<\/td><td>SOIC-8<\/td><\/tr><tr><td>TLV62565<\/td><td>TI<\/td><td>18V\/2A sync buck<\/td><td>SOT23-6<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9772","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=9772"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9772\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=9772"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=9772"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=9772"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=9772"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
