ACT86600
Hybrid PMIC for Enterprise Storage and Computing
The ACT86600 PMIC is an integrated ActivePMU power management unit. 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.
The core of the device includes 4 high power DC/DC step down converters, a lower power step down converter and a 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 single stage voltage conversion from 12V input power sources. It operates with a 2.7V to 14.4V input voltage and can withstand 16V input voltage surges. The four high current regulators can be configured as single phase outputs, or can be paralleled for up to 12A dual phase with outputs.
The ACT86600 PMIC is available in a 6 x 6 mm 48 pin QFN package.
