There are special requirements for power management in IoT applications: extending battery life up to a few years, small size to fit in a compact sensor, handling pulse loading during short periods of active time and long sleep mode and minimizing supply ripple of noise-sensitive blocks such as GPS and ultra-wide band modules. Richtek provides the comprehensive portfolio of power management products to fulfil the IoT application requirements. We also provide the product selection guide to help quickly narrow down the product selection in seconds.
