It is designed to power a wide range of processors, including Atmel’s SAMA5D2, FPGA’s, peripherals, microcontrollers, and solid-state drive applications. It is highly flexible and can be reconfigured via I2C for multiple applications without the need for PCB changes. The low external component count and high configurability significantly speeds time to market. Examples of configurable options include output voltage, startup time, slew rate, system level sequencing, switching frequency, sleep modes, operating modes etc. ACT8870 is programmed at the factory with default configuration.
