It features a wide input voltage range of 4V to 16V, configurable switching frequency (600\/800\/1000kHz), and adaptive COT control for ultrafast transient response. The device includes differential remote sense, programmable current limit, output voltage tracking, and comprehensive protection features. Available in a compact QFN-21 (3mm x 4mm) package, it is ideal for server, telecom, and POL power applications.","working_principle":"The MPQ8633BGLE-Z operates using an internally compensated constant-on-time (COT) control scheme. The high-side MOSFET turns on for a fixed on-time when the output voltage drops below the reference, then turns off and the low-side synchronous MOSFET conducts the inductor current. The adaptive COT adjusts the on-time based on input and output voltage to maintain relatively constant switching frequency. The MODE pin selects between 600kHz, 800kHz, or 1000kHz operation, and between pulse-skip mode (PSM) for light-load efficiency or forced continuous conduction mode (FCCM). Over-current protection uses valley current sensing with hiccup mode after consecutive fault cycles. The differential remote sense compensates for PCB trace resistance to maintain accurate output voltage at the load point.","pin_description":"<table><tr><th>Pin<\/th><th>Mnemonic<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>VIN<\/td><td>Input supply voltage<\/td><\/tr><tr><td>2<\/td><td>EN<\/td><td>Enable input (active high)<\/td><\/tr><tr><td>3<\/td><td>MODE<\/td><td>Frequency\/mode selection pin<\/td><\/tr><tr><td>4<\/td><td>TRK\/REF<\/td><td>Tracking\/reference voltage pin<\/td><\/tr><tr><td>5<\/td><td>FB<\/td><td>Feedback voltage input<\/td><\/tr><tr><td>6<\/td><td>DIFF<\/td><td>Differential remote sense input<\/td><\/tr><tr><td>7<\/td><td>ILIM<\/td><td>Current limit setting pin<\/td><\/tr><tr><td>8<\/td><td>PGOOD<\/td><td>Power good open-drain output<\/td><\/tr><tr><td>9<\/td><td>VCC<\/td><td>Internal 3.3V LDO output \/ external bias input<\/td><\/tr><tr><td>10<\/td><td>BST<\/td><td>Bootstrap capacitor pin<\/td><\/tr><tr><td>11-12<\/td><td>SW<\/td><td>Switch node output<\/td><\/tr><tr><td>13-18<\/td><td>VIN<\/td><td>Input supply (multiple pins for low inductance)<\/td><\/tr><tr><td>19-21<\/td><td>PGND<\/td><td>Power ground<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Server and data center POL power with 20A capability and remote sense<\/li>\n<li>Telecom base station 12V-to-low-voltage conversion with configurable frequency<\/li>\n<li>Storage system core voltage rails requiring voltage tracking and sequencing<\/li>\n<li>Game console and GPU power with adjustable current limit protection<\/li>\n<li>Networking equipment distributed power bus with PGOOD monitoring<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Difference<\/th><\/tr><tr><td>MPQ8633BGLE-P<\/td><td>MPS<\/td><td>Same part, different reel size (P vs Z)<\/td><\/tr><tr><td>MPQ8633AGLE-Z<\/td><td>MPS<\/td><td>Earlier version, different OVP behavior<\/td><\/tr><tr><td>TPS54560B<\/td><td>TI<\/td><td>5A, 60V input, lower current<\/td><\/tr><tr><td>ISL6505<\/td><td>Renesas<\/td><td>Similar 20A POL converter<\/td><\/tr><tr><td>LTM4650<\/td><td>ADI<\/td><td>uModule 25A with integrated inductor<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/9146","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=9146"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/9146\/revisions"}],"predecessor-version":[{"id":9491,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/9146\/revisions\/9491"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=9146"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=9146"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=9146"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=9146"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
