Newark is shipping Nordic Semiconductor’s new nPM1100 power management chip. The IC is designed to offer a higher efficiency-to-size ratio than other PMICs and a PCB area as low as 23mm². The PMIC suits space-constrained applications including battery charging and power delivery in hand-held, portable, wearable wireless and connected medical devices.
Designers are striving to increase battery life and add functionality without increasing form factor. Adding battery capacity incurs a volume penalty, leaving efficiency gains as the only way to achieve battery life and functionality improvements. Nordic states the nPM1100 achieves this by combining a small form factor with tight integration and efficient power conversion.
The component is a dedicated PMIC with a dual-mode configurable buck regulator and integrated battery charger. It is designed as a complementary component to Nordic Semiconductor’s nRF52 and nRF53 series of SoCs, which enable reliable power delivery and stable operation while maximizing battery life through high efficiency and low quiescent currents.
