The ZL6105ALAFTR5546 is a digital power controller with integrated MOSFET drivers. Auto compensation eliminates the need for manual compensation design work. Adaptive performance optimization algorithms improve power conversion efficiency. Zilker Labs Digital-DC™ technology enables a blend of power conversion performance and power management features.The ZL6105ALAFTR5546 is designed to be a flexible building block for DC power and can be easily adapted to designs ranging from a single-phase power supply operating from a 3.3V to a multiphase current sharing supply operating from a 12V input. The ZL6105ALAFTR5546 eliminates the need for complicated power supply managers as well as numerous external discrete components.The ZL6105ALAFTR5546 uses the I2C/SMBus™ with PMBus™ protocol for communication with a host controller and the Digital-DC bus for communication between Zilker Labs devices.The ZL6105ALAFTR5546 is pin for pin compatible with the ZL2008. The POLA VOUT table and compensation table have been removed. A new single resistor VOUT table and the Auto Compensation feature have been added.
