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 3.3 V input to a multi-phase supply operating from a 12 V 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.

ZL2008主要优势:

Performance: The ZL2008 is the only digital power controller on the market that has been proven to outperform analog controllers in terms of efficiency.  This is made possible by advanced algorithms that constantly optimize the power supply performance in real time.

Design flexibility: Configuration can be done by pin strap, resistor encoding, or PMBus.  A high level of integration plus flexible configuration makes the product extremely easy to design-in.

Suitability for an application: By combining power conversion, power management, fault management and telemetry capabilities, the ZL2008 is ideally suited for a wide range of applications.
