PCA9421UKZ NXP PMIC | 25-WLCSP (2.09x2.09) | 1.8V-5.5V Input, 3 Buck Converters

Product Overview

The PCA9421UKZ is a highly integrated power management IC (PMIC) from NXP Semiconductors, designed for space-constrained portable and wearable applications. Housed in a compact 25-WLCSP (2.09x2.09 mm) package, it provides a complete power solution with high efficiency and low quiescent current. The device integrates three buck converters, one boost converter, and two low-dropout regulators (LDOs), all configurable via I2C interface. It supports input voltages from 1.8V to 5.5V, making it suitable for single-cell Li-ion battery-powered devices.
