EUP3420是同步电流模式降压直流-直流转换器,能提供2与优秀的线和负载调节负载电流。操作之间的输入电压范围2.7 v和5.5 v,设备是理想的便携式应用程序由一个由3芯锂电池或镍氢/镍镉电池。EUP3420运行在1.5 mhz固定频率脉宽调制模式,提供了非常低的输出纹波电压噪声敏感的应用程序。内部集成同步开关增加效率,而不需要一个外部的肖特基二极管。EUP3420可用在10-pin MSOP和10-pin TDFN包。典型应用电路特性z z效率高96%到300μa典型的静态电流负载电流z z 1.5 mhz恒定开关频率z z 2.7 v至5.5 v的输入电压范围可调输出电压z 100%的关税低至0.7 v循环低辍学操作不需要肖特基二极管z短路和热保护优秀的线和负载瞬态响应z 1μa关闭当前z内置软启动z z MSOP-10和TDFN-10包中可用铅(Pb)——通过无铅认证和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. Typical Application Circuit FEATURES z High Efficiency up to 96% z Up to 2A Load Current z 300μA Typical Quiescent Current z 1.5MHz Constant Switching Frequency z 2.7V to 5.5V Input Voltage Range z Adjustable Output Voltage as Low as 0.7V z 100% Duty Cycle Low Dropout Operation z No Schottky Diode Required z Short Circuit and Thermal Protection z Excellent Line and Load Transient Response z 1μA Shutdown Current z Built-In Soft-Start z Available in MSOP-10 and TDFN-10 Package z RoHS Compliant and 100% Lead(Pb)-Free
