AP1603 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 Lead-Free Packages: SOT26 Lead Free Finish/RoHS Compliant for Lead Free products (Note 1) General Description The AP1603 is a high efficiency step-up DC/DC converter for applications using as few as a single NiMH or Li-Ion battery cells. Only four external components are required to deliver a fixed output voltage of 3.3V. The AP1603 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 150KHz (max.) switching rate results in smaller passive components. The space saving SOT26 packages make the AP1603 an ideal choice of DC/DC converter for space conscious applications, like pagers, electronic cameras, and wireless microphones.

AP1603
1. 物料型号: - 型号为AP1603,是一款升压型DC/DC转换器。

2. 器件简介: - AP1603是一款高效率的升压DC/DC转换器,适用于使用至少一个镍氢或锂离子电池单元的应用。它只需要四个外部组件即可提供固定的3.3V输出电压。该器件从低于0.9V的输入电压开始工作,并具有脉冲频率调制(PFM)方案,优化了轻负载输出和低输入电压应用的性能。

3. 引脚分配: - FB(反馈):用于输出电压的反馈。 - GND(地):接地引脚。 - REF(1.2V参考电压):需要与0.1μF电容器旁路。 - LX(N沟道和P沟道功率MOSFET漏极):用于开关电压。 - OUT(电源输出):提供自举电源至IC。 - SHDN(关闭输入):高电平(>80% Vout)为工作模式,低电平(<20% Vout)为关闭模式。

4. 参数特性: - 供电电压(Vcc):-0.3至5.5V。 - 输出电流(Iout):-0.8至0.2A。 - 存储温度范围(Tsr):-65至+150°C。 - 工作温度范围(ToP):-40至+85°C。

5. 功能详解: - AP1603通过PFM控制电路工作,在最大150kHz的开关频率下,能够实现更小的被动组件。该器件设计用于最大化便携产品的电池寿命,并仅在需要服务负载时切换,以最小化开关损失。

6. 应用信息: - 适用于寻呼机、相机、无线麦克风、口袋型组织者、电池备份供应商和便携式仪器等空间受限的应用。

7. 封装信息: - 封装类型为SOT26,是一种节省空间的无铅封装,符合RoHS标准。
