The ZL2004 is a digital DC-DC controller designed to work with the ZL1505 MOSFET driver IC. 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-DCTM technology enables a blend of power conversion performance and power management features.

The ZL2004 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 4.5 V input to a multi-phase supply operating from a 12V input. The ZL2004 eliminates the need for complicated power supply managers as well as numerous external discrete components.

All operating features can be configured by simple pinstrap/ resistor selection or through the SMBusTM serial interface. The ZL2004 uses the PMBusTM protocol for communication with a host controller and the Digital- DC bus for communication between other Zilker Labs devices.
