ZL2006 Functional Diagram
Description
The ZL2006 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 across the entire load range. Zilker Labs Digital-DC™ technology enables a blend of power conversion performance and power management features. The ZL2006 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 ZL2006 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 SMBus™ serial interface. The ZL2006 uses the PMBus™ protocol for communication with a host controller and the Digital- DC bus for communication between other Zilker Labs devices.

- Application NotePDF 805 KB an2018 May 15, 2018AI-generated Summary: The ZL_PMBus API provides functions to interact with Zilker Labs PMBus devices, including retrieving the DLL version, firmware version, and scanning connected devices. The ZL_DLLVersion function returns the API DLL version, while ZL_FWVersion obtains the firmware version from a device handle. ZLDeviceScan lists all connected PMBus interfaces by their serial numbers, requiring memory allocation based on the number of devices found. Proper error handling and usage conditions are described for each function.
- Application NotePDF 214 KB an2037 May 09, 2018AI-generated Summary: The checklist covers schematic design, PCB layout, and PMBus configuration for Zilker Labs power devices. It emphasizes verifying device pin-straps, SMBus addressing, pull-up resistors, and synchronization of switching clocks. It recommends proper decoupling, temperature compensation, and component selection for efficiency and thermal performance. PMBus configuration includes sequence settings, fault responses, calibration, temperature measurement, and command protection with specific password lengths. Proper documentation and adherence to design guidelines ensure reliable system performance.
- Application NotePDF 807 KB an2035 May 09, 2018AI-generated Summary: Compensation involves canceling poles with zeros to simplify system response, balancing bandwidth for transient response and noise sensitivity. A Type 3 PID compensator modifies the error signal with proportional, integral, and derivative feedback to control the PWM generator. Digital PID compensation offers flexibility using G, F, and Q coefficients to match compensator and plant characteristics. Stability depends on phase and gain margins, with typical targets of 45° phase margin and 6 dB gain margin. The CompZL tool aids initial compensation by modeling the plant and adjusting parameters to optimize stability and transient performance.
- Application NotePDF 573 KB an2032 May 08, 2018AI-generated Summary: The document explains the Non-Linear Response (NLR) configuration for DDC products, detailing threshold settings, correction times, and operating modes. Inner and outer thresholds adjust voltage response to load changes, with correction times proportional to switching periods. Three NLR modes—single level, two level, and hysteretic—offer flexibility based on power filter damping. Blanking time prevents rapid switching. Typical application circuits illustrate these concepts.
