Tiny PMIC targets wearables

Operating with battery voltages down to 0.7 V, the MAX20310 PMIC from Maxim combines two buck-boost outputs with two LDO linear regulators and power-management features like a push-button monitor and sequencing controller. According to the manufacturer, the PMIC allows designers of primary-cell wearable medical and fitness devices to reduce solution size by as much as 50%.

The tiny MAX20310 uses a single-inductor, multiple-output architecture that integrates four power outputs from a single inductor, each with ultra-low quiescent current. This high integration not only halves solution size, but also slashes quiescent current consumption by over 40% during sleep or standby mode compared to discrete solutions.
