♠Active-Clapped, Spread-Spectrum, Current-Mode PWM Controllers
O le MAX5974_ e tu'uina atu ai le fa'atonuga mo le lautele-fa'aofi-voltage, fa'agaoioi-fa'apipi'i, o le taimi nei-mode PWM, liliu i luma i le Power-over-Ethernet (PoE) powered device (PD) applications. O le MAX5974A/MAX5974C e fetaui lelei mo le lautele poʻo le telefoni faʻaoga, ae o le MAX5974B/ MAX5974D e faʻaogaina foi le eletise maualalo maualalo i lalo i le 10.5V.
O masini e aofia ai le tele o mea e faʻaleleia ai le faʻaogaina o le sapalai. E toe fa'aaogaina e le aveta'avale AUX le tau fa'amaneta nai lo le fa'ama'imau i se ta'amilosaga fa'amau fa'aletonu. Taimi e mafai ona fa'apolokalameina i le va o le AUX ma le aveta'avale autu e fa'atagaina ai le suiga ole-voltage (ZVS). I lalo o tulaga mama-avega, o masini e faʻaitiitia ai le fesuiaʻiga o taimi (faʻasolosolo taimi) e faʻaitiitia ai le gau o suiga.
O le MAX5974A/MAX5974B o loʻo faʻaalia ai le taʻavale tulaga ese e ausia ai tulafono faatonutonu e aunoa ma le faʻaogaina o se optocoupler, ae o le MAX5974C/MAX5974D e faʻaogaina le auala masani o le optocoupler feedback. O se mea faʻapipiʻi faʻalavelave i totonu ma le 1% faʻamatalaga e aoga tele i le mamanu e le faʻaogaina, e faʻaumatia ai le manaʻoga mo se faʻatonuina o le shunt fafo.
O masini o lo'o fa'aalia ai se fa'aoga tulaga ese fafaga-i luma tiute-ta'amilosaga pito sili ona maualuga e fa'atupu ai le maualuga o le pipii volt tausaga i taimi le tumau e tuto'atasi mai le laina volt, fa'ataga le fa'aogaina o le MOSFET malosi ma lalo ifo le gau gau. O le fa'aogaina o alaleo e mafai ona fa'apolokalameina e maua ai le fa'aogaina o alaleo maualalo-EMI.
Ole MAX5974_ o lo'o maua ile 16-pin TQFN-EP pack tausaga ma fa'amauina mo le fa'agaioiga i luga ole -40°C i le +85°C ma le -40°C i le +125°C le vevela.
