Qorvo ACT88422 ActiveCiPS™ PMICs
Qorvo ACT88422 ActiveCiPS™ Power Management Integrated Circuits (PMICs) operate a wide range of processors, including solid-state drive applications, video processors, FPGAs, peripherals, and microcontrollers.
The ACT88422 offers 3-State GPIOs and I2C communication, allowing multiple configurations without PCB changes. The low external component count and high configurability significantly speed up the time to market. Examples of configurable options include output voltage as low as 0.5V, startup time, slew rate, system-level sequencing, switching frequency, low power modes, operating modes, etc.
The Qorvo ACT88422 PMICs include four DC/DC step-down converters with integrated power FETs and two low-dropout regulators (LDOs). Buck1, LDO1, and LDO2 can be configured as load switches, and Buck4 can be configured as an LDO. Each DC/DC regulator needs only three small components for operation, and the LDOs only require two small ceramic capacitors. All outputs are highly configurable through the I2C interface.
