The ZL8101 is a digital PWM controller with auto compensation that is designed to work with either the ZL1505 MOSFET driver IC, ISL6611 Phase Doubler IC, or DrMOS type devices. 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 across the entire load range. Zilker Labs Digital-DC™ technology enables a blend of power conversion performance and power management features. The ZL8101 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 4. 5V input to a multi-phase supply operating from a 12V input. The ZL8101 eliminates the need for complicated power supply managers as well as numerous external discrete components. Most operating features can be configured by simple pin-strap/resistor selection or through the SMBus™ serial interface. The ZL8101 uses the PMBus™ protocol for communication with a host controller and the Digital-DC bus for communication between other Zilker Labs devices.
