说明

MAX77827为高效率升/降压转换器,适用于单节锂离子供电应用,6μA典型静态电流为业界最低。器件支持1.8V至5.5V输入电压范围,输出电压范围为2.3V至5.3V。IC提供两种不同的开关电流(1.8A和3.1A),根据给定的负载电流需求优化外部元件尺寸。使用1.8A开关限流选项时,IC在降压模式下可支持高达1.0A负载电流,在升压模式下(VIN = 3.0V,VOUT = 3.3V)支持900mA负载电流。

为电池供电的便携式应用提供电源轨的DC/DC转换器方案中,96%峰值效率使该IC成为最佳选择之一,

IC具有可调节输出电压功能,可通过单个电阻在2.3V至5.3V范围内设置。2个GPIO引脚支持强制PWM使能和电源就绪(POK)指示。独特的控制算法允许高效、卓越的电源/负载瞬态响应,以及在降压和升压模式之间平稳切换。这些性能可以提供设计上的灵活性,允许IC覆盖较宽的应用范围和应用场景,同时最大程度减小电路板面积。

MAX77827采用1.61mm x 2.01mm、12焊球晶圆级封装(WLP)。
