High-Efficiency Boost Converter Extends Wearable Medical Patch Battery Life

By: Nazzareno Rossetti

Abstract: Wearable medical devices are transforming the healthcare industry by continuously recording and transmitting the patient state of health. They must be unobstructive and last several days relying on small, disposable batteries. This design solution reviews the shortcomings of a typical power management solution for wearable medical patches and introduces a new, high-efficiency, low-quiescent boost converter that meets the specified operating life.
