说明

MAX15022是带有双LDO控制器的双通道、脉宽调制(PWM)降压型DC-DC调节器。该器件工作在2.5V至5.5V输入电压范围,每通道输出电压可在0.6V与输入电压(VAVIN)之间调节。MAX15022采用双LDO控制器,能够提供高达4A (调节器1)和2A (调节器2)的输出电流,LDO控制器用于驱动两个外部PNP晶体管,提供两路额外的输出。该器件还能够在500kHz至4MHz之间调节开关频率,从而在尺寸和性能之间进行平衡,实现优化设计。

MAX15022采用具有外部补偿功能的电压模式控制架构,提供优异的噪声抑制,并可灵活选择电感值和电容类型。两路开关调节器可工作在180°错相模式,能够大大降低输入波纹电流的RMS,减小输入旁路电容的尺寸。

在上电和掉电过程中,MAX15022具有跟踪(同步/比例)或排序功能。上电排序时,器件能够无干扰地进入预偏置输出。

此外,器件还可提供带有滞回的欠压锁定和数字软启动/软停止功能,上电和断电过程中无脉冲干扰。保护功能包括无损耗逐周期限流、打嗝模式输出短路保护以及过热关断。

MAX15022提供节省空间的5mm x 5mm、28引脚TQFN-EP封装,工作于-40°C至+125°C温度范围。
