nPM1100 Power Management IC

Pin configurable and compact form-factor PMIC

The nPM1100 is a Power Management IC (PMIC) combining an integrated battery charger with a dual-mode configurable buck regulator. The nPM1100 simplifies power supply design while delivering high conversion efficiency and low quiescent current to maximize battery life in space-constrained wearable, medical, and IoT applications. It is 100 % pin configurable and does not require any software for configuration or control. 

With a total solution footprint as low as 23 mm² including all passive components, the nPM1100 enables compact battery-powered designs that previously required multiple discrete components. PCB area is slightly larger for efficiency optimized designs.
