nPM1100 Power Management ICs Nordic Semiconductor nPM1100 Power Management ICs combine a PMIC, dual-mode configurable buck regulator, and integrated battery charger. The nPM1100 is a natural companion to Nordic’s nRF52 Series and nRF53 Series System-on-Chips (SoCs’) but is also well suited for any product with a small rechargeable battery. This design ensures reliable power delivery and stable operation while maximizing battery life through high efficiency and low quiescent currents.
