AP1601 Step-Up DC/DC Converter Features -A Guaranteed Start-Up from less than 0.9 V. -High Efficiency. -Low Quiescent Current. -Less Number of External Components needed. -Low Ripple and Low Noise. -Space Saving Packages: MSOP-8L and MSOP-10L. General Description The AP1601 is a high efficiency step-up DC/DC converter for applications using 1 to 4 NiMH battery cells. Only three external components are required to deliver a fixed output voltage of 3.3V or 5V. The AP1601 starts up from less than 0.9V input with 1mA load. Pulse Frequency Modulation scheme brings optimized performance for applications with light output loading and low input voltages. The output ripple and noise are lower compared with the circuits operating in PSM mode. The PFM control circuit operating in 100KHz (max.) switching rate results in smaller passive components. The space saving MSOP packages make the AP1601 an ideal choice of DC/DC converter for space conscious applications, like pagers, electronic cameras, and wireless microphones. Applications -Pagers. -Cameras. -Wireless Microphones. -Pocket Organizers. -Battery Backup Suppliers. -Portable Instruments. Pin Assignments Pin Descriptions Name Description Use a resistor network to set the output voltage from +2.0V to +5.5V. If FB=Vout, Vout=3.3V fix voltage FB=GND, Vout=5V fix voltage Low-Battery Comparator Input. Internally set to trip at +1.30V. Open-Drain Low-Battery Comparator Output. Connect LBO to OUT through a 100kΩ resistor. Output is low when VLBI is 80% of VOUT) for operating mode. Drive low (

物料型号: - 型号为AP1601,是一款升压型DC/DC转换器。

器件简介: - AP1601专为使用1至4节镍氢电池单元的应用而设计,仅需三个外部元件即可提供固定的3.3V或5V输出电压。该器件从低于0.9V的输入电压开始工作,并在轻负载输出和低输入电压的应用中提供优化的性能。

引脚分配: - FB(反馈引脚):用于设定输出电压,可以设定在+2.0V至+5.5V之间。如果FB=Vout,则输出电压固定为3.3V;如果FB=GND,则输出电压固定为5V。 - LBO(低电池比较器输出):当VLBI小于1.2V时输出低电平。 - REF(1.2V参考电压):需要用0.1µF电容旁路。 - OUT(电源输出):提供自举电源。 - LX(N沟道和P沟道功率MOSFET漏极)。 - GND(地)。 - SHDN( shutdown输入):高电平(>80%的VOUT)为工作模式,低电平(<20%的VOUT)为关闭模式。 - CLSEL(电流限制选择输入):CLSEL=GND时电流限制为0.8A,CLSEL=OUT时电流限制为0.4A。 - BATT(电池连接):如果不使用阻尼开关,可以不连接BATT。

参数特性: - 供电电压(Vcc):-0.3至8.0V。 - 电池电压(VBATT):-0.3至6.0V。 - 开启电压:0.9V(典型值)。 - 输出电压范围:2至5.5V。 - 稳态输出电流:在3.3V输出时,CLSEL=OUT的条件下为300mA至420mA,CLSEL=GND的条件下为150mA至220mA。

功能详解: - AP1601采用脉冲频率调制(PFM)方案,在轻负载和低输入电压下提供优化性能。PFM控制电路以最高100kHz的开关速率工作,使得被动元件更小,MSOP封装使得AP1601成为空间受限应用的理想选择。

应用信息: - 应用领域包括传呼机、相机、无线麦克风、口袋型组织器、电池备份电源和便携式仪器。
