说明

MAX15039是一款高效开关调节器,输出电压范围为0.6V至VIN的90%,可提供高达6A的负载电流。器件工作电压为2.9V至5.5V,非常适合负载点和后续稳压应用。在整个负载、输入电压和温度变化范围内,器件输出电压总误差低于±1%。

MAX15039采用固定频率PWM工作模式,开关频率可通过外部电阻设置在500kHz至2MHz范围。MAX15039提供可选的跳脉冲模式工作,以提高轻载效率。高工作频率允许全陶瓷电容设计,同时也允许采用小尺寸外部元件。

片内低导通电阻nMOS开关保证在较重负载下提供高效率,并使电感值最小。相对于分立元件方案,该器件的电路布局要简单得多。简单的电路布局和引脚配置保证器件在新设计中的一次通过率。

MAX15039内部集成了宽带(28MHz)电压误差放大器。电压模式控制结构和误差放大器允许使用III类补偿方案,使环路最大带宽达到开关频率的20%。较宽的环路带宽能够保证快速瞬态响应,从而减小所需的输出电容,允许全陶瓷电容设计。

MAX15039具有两个三态逻辑输入,用于选择9种不同的输出电压。这些预设输出电压为客户提供±1%的输出电压精度,无需使用昂贵的0.1%精密电阻。另外,可以通过连接在反馈端的两个外部电阻,配合0.6V内部基准或REFIN输入端施加的外部基准,将输出电压设置到用户需要的任何数值。MAX15039通过外部电容编程软启动时间,以减少输入浪涌电流。
