SIMO电压调节器

利用开关转换器的高效率,具有适用于多电源轨应用的单个电感设计的紧凑性和节省空间特性。ADI公司的单电感多输出(SIMO)电源管理IC系列使用一个电感来提供多个开关降压-升压调节器。高效转换有利于延长电池寿命,超紧凑的尺寸和低物料成本则为空间有限的可穿戴设备、耳机、物联网和其他电池供电的小型消费电子设备提供非常合用的解决方案。附加的集成功能和特性进一步简化了低功耗便携式设备的设计,是通过集成电池管理(充电器和燃油表)、对噪声敏感的电源轨的LDO输出,以及用于控制上电和关断的板载时序控制器等功能实现的。I2C接口提供完全定制电源管理IC的能力,支持动态电压调节(DVS),以实现进一步节能和自定义的电源使用。

SIMO in PMICs

Our new power management ICs (PMICs), the MAX77650 and MAX77651, were designed with micropower SIMO buck-boost DC-DC converters. An integrated 150mA LDO in the PMICs provides ripple rejection for noise-sensitive applications. In the MAX77650/MAX77651, the SIMO provides three independently programmable power rails from a single inductor for an innovative power management solution. The high integration of SIMO architecture helps significantly reduce the overall solution size compared to other discrete solutions.
