EUP3420是同步電流模式降壓直流-直流轉換器,能提供2與優(yōu)秀的線和負載調節(jié)負載電流。操作之間的輸入電壓范圍2.7 v和5.5 v,設備是理想的便攜式應用程序由一個由3芯鋰電池或鎳氫/鎳鎘電池。EUP3420運行在1.5 mhz固定頻率脈寬調制模式,提供了非常低的輸出紋波電壓噪聲敏感的應用程序。內部集成同步開關增加效率,而不需要一個外部的肖特基二極管。EUP3420可用在10-pin MSOP和10-pin TDFN包。典型應用電路特性z z效率高96%到300μa典型的靜態(tài)電流負載電流z z 1.5 mhz恒定開關頻率z z 2.7 v至5.5 v的輸入電壓范圍可調輸出電壓z 100%的關稅低至0.7 v循環(huán)低輟學操作不需要肖特基二極管z短路和熱保護優(yōu)秀的線和負載瞬態(tài)響應z 1μa關閉當前z內置軟啟動z z MSOP-10和TDFN-10包中可用鉛(Pb)——通過無鉛認證和100%

The EUP3420 is a synchronous current mode step-down dc-dc converter, capable of delivering 2A load current with excellent line and load regulation. Operating with an input voltage range between 2.7V and 5.5V, the device is ideal for portable applications powered by a single Li-Ion battery cell or by 3-cell NiMH/NiCd batteries. The EUP3420 operates at 1.5MHz fixed frequency PWM mode and provides very low output ripple voltage for noise sensitive applications. The internal integrated synchronous switch increases efficiency while eliminates the need for an external Schottky diode. The EUP3420 is available in the 10-pin MSOP and 10-pin TDFN package.
