Digital DC-DC Controller with Drivers and Pin-Strap Current Sharing

The ZL2008 is a digital DC/DC controller with integrated MOSFET drivers. Current sharing allows multiple devices to be connected in parallel to source loads with very high current demands. 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 ZL2008 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 input to a multi-phase supply operating from a 12V input. The ZL2008 eliminates the need for complicated power supply managers as well as numerous external discrete components. Key operating features can be configured by pin-straps, including compensation, current sharing and output voltage. The ZL2008 uses the I2C/SMBus™ with PMBus™ protocol for communication with a host controller and the Digital-DC bus for communication between Zilker Labs devices.
