nPM1100 Power Management IC

The nPM1100 is a dedicated power management IC (PMIC) with a dual-mode configurable buck regulator and integrated battery charger. It is designed as a complementary component to Nordic's nRF52® Series and nRF53® Series system on chips (SoCs) to ensure reliable power delivery and stable operation while maximizing battery life through high efficiency and low quiescent currents.

The dual-mode regulator operates at up to 92% power conversion efficiency, prolonging the battery life of any nRF52 or nRF53 SoC-based application using a rechargeable battery. Hysteretic mode reduces current consumption for low load conditions, while PWM mode allows for cleaner power operation and better performance for higher loads. The regulator can deliver up to 150 mA, efficiently providing ample current for the nRF52 or nRF53 Series SoCs plus additional circuitry.

The device can also be used as a generic PMIC for any rechargeable application. Its extremely compact form factor makes it ideal for advanced wearables, connected medical devices, and other size-constrained applications. When optimized for size, PCB area usage can be as low as 23 mm² with passive components included. This increases to approximately 27 mm² when optimized for performance.
