It uses D-CAP+ (Direct Capacitor-Available Plus) control mode, a proprietary constant-on-time architecture with adaptive voltage positioning. Unlike voltage-mode or current-mode control, D-CAP+ does not require external compensation for most output capacitor combinations. The on-time is modulated inversely with VIN to maintain pseudo-constant frequency. The error amplifier compares FB against a 0.6V reference and adjusts the on-time to regulate output voltage. The low-side MOSFET operates synchronously during the off-time, eliminating diode conduction losses and improving efficiency to 95%. The device supports 500kHz or 300kHz switching. Over-current protection monitors the low-side MOSFET voltage drop for valley current limiting.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1-3<\/td><td>PGND<\/td><td>Power<\/td><td>Power ground for low-side FET<\/td><\/tr><tr><td>4-6<\/td><td>SW<\/td><td>Output<\/td><td>Switching node (inductor connection)<\/td><\/tr><tr><td>7<\/td><td>VBST<\/td><td>Analog<\/td><td>Bootstrap for high-side driver<\/td><\/tr><tr><td>8<\/td><td>VIN<\/td><td>Power Input<\/td><td>Input supply (1.5-15V)<\/td><\/tr><tr><td>9<\/td><td>COMP<\/td><td>Analog<\/td><td>Error amplifier output\/compensation<\/td><\/tr><tr><td>10<\/td><td>FB<\/td><td>Input<\/td><td>Feedback (0.6V reference)<\/td><\/tr><tr><td>11<\/td><td>SS<\/td><td>Analog<\/td><td>Soft-start capacitor<\/td><\/tr><tr><td>12<\/td><td>PWGD<\/td><td>Output<\/td><td>Power good indicator<\/td><\/tr><tr><td>13<\/td><td>EN<\/td><td>Input<\/td><td>Enable (active high)<\/td><\/tr><tr><td>14-22<\/td><td>AGND\/PAD<\/td><td>Power<\/td><td>Analog ground and thermal pad<\/td><\/tr><\/table>","application_scenarios":"<li>Industrial control<\/li><li>Consumer electronics<\/li><li>Communication equipment<\/li><li>Power management<\/li>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>Texas Instruments<\/td><td>TPS53355DQPR<\/td><td>VQFN-22<\/td><td>30A version, same family<\/td><\/tr><tr><td>Analog Devices<\/td><td>LTC3616EUDD<\/td><td>QFN-24<\/td><td>6A, 4-36V, polyphase<\/td><\/tr><tr><td>Infineon<\/td><td>IR3899MTRPBF<\/td><td>PQFN-4x5<\/td><td>8A, 4.5-14V, integrated<\/td><\/tr><tr><td>Texas Instruments<\/td><td>TPS54560BDDAR<\/td><td>HSOIC-8<\/td><td>5A, 4.5-60V buck<\/td><\/tr><tr><td>Monolithic Power<\/td><td>MP8759GD-Z<\/td><td>QFN-22<\/td><td>5A, 5-36V<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/5765","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=5765"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/5765\/revisions"}],"predecessor-version":[{"id":5915,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/5765\/revisions\/5915"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=5765"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=5765"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=5765"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=5765"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
