The ACT86600 PMIC is an integrated?ActivePMU power management unit. It is highly flexible with multiple time programmable configuration bits that allow digital or software control without the necessity for board level component changes. The configuration settings can be reconfigured via I2C, which allows the same device to be optimized for multiple applications. Each regulator contains dedicated registers that allow it to be optimized for system or application critical requirements such as efficiency, fast dynamic response, solution size or output voltage range. The low external component count and high configurability significantly speeds time to market. Examples of configurable options include output voltage, current limit, enable and triggering signals, startup time, slew rate, system level sequencing, switching frequency, sleep modes, operating modes, output fault detection, interrupt generation etc.?

The core of the device includes 4 high power DC/DC step down converters, a lower power 5V step down converter, and a 12V buck-boost converter.? Each regulator can be configured for a wide range of output voltages through the I2C interface.?

The ACT86600 is a high voltage PMIC that is optimized for 12V input single stage voltage conversion down to 0.6V. It operates over a wide input voltage range of 2.7V to 14.4V and can withstand 16V input voltage surges. The four high current regulators can be configured as single-phase 4A and 6A outputs, or they can be operated in parallel to provide 8A and 12A outputs.?

The ACT86600 PMIC is available in a 6 x 6 mm 48 pin QFN package.?
