♠ TPS6229x 1-A Step Down Converter ho 2 x 2 DRV Package
Lisebelisoa tsa TPS6229x li sebetsa hantle haholo li-converter tsa DC/DC tse ntlafalitsoeng bakeng sa lits'ebetso tse nkehang tse tsamaisoang ke betri. Ba fana ka tlhahiso ea hona joale ea 1000-mA ho tloha seleng e le 'ngoe ea Li-ion.
Ka mefuta ea motlakase e kenang ea 2.3 V ho isa ho 6.0 V, lisebelisoa li tšehetsa libeteri tse nang le mefuta e mengata ea motlakase 'me li loketse ho kenya matla lits'ebetsong tse nkehang joaloka mehala ea cellular le lisebelisoa tse ling tse nkehang habonolo.
Lisebelisoa tsa TPS6229x li sebetsa ka lebelo le tsitsitseng la 2.25-MHz 'me li kenya ts'ebetso ea mokhoa oa ho boloka matla ho maqhubu a boima bo bobebe ho boloka ts'ebetso e phahameng holim'a mefuta eohle ea hona joale ea mojaro.
Mokhoa oa ho boloka matla o ntlafalitsoe bakeng sa ripple ea motlakase o tlase. Bakeng sa lits'ebetso tsa lerata le tlase, lisebelisoa li ka qobelloa ho kena mokhoeng o tsitsitseng oa frequency pulse wide modulation (PWM) ka ho hulela phini ea MODE holimo. Ka mokhoa oa ho koala, tšebeliso ea hona joale e fokotsehile ho tlase ho 1 μA. Lisebelisoa tsa TPS6229x li lumella tšebeliso ea li-inductors tse nyane le li-capacitor ho fihlela boholo bo nyane ba tharollo.
Lisebelisoa tsa TPS6229x li sebetsa holim'a mocheso oa moea o sa lefelloeng oa -40°C ho isa ho 85°C. Lisebelisoa li fumaneha ka har'a sephutheloana sa 2-mm × 2-mm 6-pin WSON (DRV).
