ACT88329VU101-T

Overview

The Qorvo ACT88329VU101-T is an Advanced Constant On-Time (COT) Power Management IC (PMIC) from the ActiveCiPS™ series. It integrates three buck converters, two Low Dropout (LDO) regulators, and a load bypass switch within a compact 2.18mm x 2.58mm 30-ball WLCSP package. The device supports an input voltage range of 2.7 V to 5.5 V. Key electrical specifications include a 4 A buck converter with bypass functionality, a second 4 A buck converter, and a 2 A buck converter. Additionally, it features two 300 mA LDOs. The operating junction temperature range extends from -40°C to +125°C.
