SIMO Regulators

SIMO Regulators

Harness the high efficiency of switching converters with the compact, space-saving architecture of a single inductor design for multipower rails applications. Analog Devices’ family of single inductor multiple outputs (SIMO) power management ICs provides multiple switching buck-boost regulators using only one single inductor. The high-efficiency conversions benefit and extend battery life, while the ultracompact size and low bill of materials provide a perfect solution for space constrained wearables, hearables, IoT, and other small form factor battery-powered consumer devices.
Additional integrated functionalities and features further simplify the design of low power portable devices by integrating functions such as battery management (charger and fuel gauging), LDO outputs for noise- sensitive rails, and on-board sequencer for controlled power-up and power-down. An I²C interface provides the capability to completely customize enables complete customization of the power management IC and supports dynamic voltage scaling (DVS) for additional power savings and custom power profiles.

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.
