PCA9420AUKZ NXP PMIC | 25-WLCSP (2.09x2.09) | 1.8V-5.5V Input, 3 Buck Converters

Product Overview

The PCA9420AUKZ is a highly integrated power management IC (PMIC) from NXP Semiconductors, designed for space-constrained and power-sensitive applications. Housed in a compact 25-WLCSP (2.09x2.09 mm) package, it integrates three step-down DC-DC converters, two low-dropout regulators (LDOs), and a battery charger, all controlled via an I2C interface. This device supports input voltages from 1.8V to 5.5V, making it suitable for single-cell Li-ion battery-powered systems. With high efficiency and low quiescent current, the PCA9420AUKZ is ideal for portable electronics, IoT devices, and wearable technology.
