Qorvo ACT88320 PMICs with Inrush Control & Bypass Switch

Qorvo ACT88320 Power Management ICs (PMICs) with Inrush Control and Bypass Switch are integrated ActivePMU™ power management units. These PMICs are highly flexible and can be reconfigured via I²C for multiple applications without the need for PCB changes. Examples of configurable options include output voltage, startup time, system-level sequencing, switching frequency, sleep modes, and operating modes. The core of these PMICs includes three DC/DC step-down converters using integrated power FETs and two low drop-out regulators (LDOs). The ACT88320 PMICs are available in a 4mm x 4mm 32-pin QFN package. These PMIC devices are ideal for usage in solid-state drives, field-programmable gate arrays (FPGAs), personal navigation devices, and microcontroller applications.
