♠ TPS54302 4.5-V kusvika 28-V Input, 3-A Output, EMI-Friendly Synchronous Step-Down Converter
Iyo TPS54302 mudziyo ndeye 4.5-V kusvika 28-V yekuisa voltage renji, 3-A synchronous buck converter. Chishandiso ichi chinosanganisira maviri akabatanidzwa switching FETs, yemukati loopmuripo, uye 5-ms yemukati yakapfava inotanga kuderedza chikamu chechikamu.
Nekubatanidza maMOSFET uye nekushandisa iyo SOT-23 package, iyo TPS54302 mudziyo inowana yakakwira simba density uye inopa diki tsoka paPCB.
Yepamberi Eco-modhi yekumisikidza inokwidziridza kurongeka kwechiedza uye inoderedza kurasikirwa kwemagetsi.
MuTPS54302 mudziyo, iyo frequency kuparadzira spectrum mashandiro inounzwa yekudzikisa EMI.
Cycle-by-cycle yazvino muganho mune ese ari maviri-parutivi MOSFET inochengetedza inoshandura mune yakawandisa mamiriro uye inosimudzirwa neyakaderera-padivi MOSFET freewheeling ikozvino muganho unodzivirira kutiza kwazvino. Hiccup mode dziviriro inokonzereswa kana iyo overcurrent mamiriro akaenderera kwenguva yakareba kupfuura yazvino nguva.
• 4.5-V kusvika 28-V yakafara yekuisa voltage renji
• Yakabatanidzwa 85-mΩ uye 40-mΩ MOSFETs ye3-A, inoenderera inobuda ikozvino
• Yakaderera 2-μA kuvhara, 45-μA inonyarara ikozvino
• Mukati 5-ms yakapfava kutanga
• Yakagadziriswa 400-kHz switching frequency
• Frequency kupararira spectrum kuderedza EMI
