The Nordic Semiconductor integrated Power Management IC (PMIC) has a linear-mode lithium-ion or lithium-polymer battery charger with standard terminal voltage in a compact 4.0x4.0 mm QFN package. It has a highly efficient DC/DC buck regulator with configurable dual mode output. The nPM1100 is an extremely compact PMIC device, created for space constrained applications that have a small lithium-ion or lithium-polymer battery. It is compatible with all nRF52 and nRF53 Series SoCs, supports charging batteries at up to 400 mA through USB, and delivers up to 150 mA of current to power external components with regulated voltage.
