The UCD9112 is dual-phase synchronous buck digital PWM controller that supports point of load (POL) applications. The device is configured thru the use of a graphical user interface (GUI). The loop compensator is configurable with the GUI to meet dynamic converter performance allowing a single hardware design to cover a broad range of POL applications.
In addition to digital control loop, the UCD9112 is able to monitor and manage power supply operatingconditions and report the status to the host systemthrough PMBus. The management parameters are configurable through GUI. The GUI also allows the power supply designer to easily configure the digitalcontrol loop characteristics and generate the gain and phase information for analysis using bode plots.
To ensure balanced outputs on each phase, the UCD9112 incorporates a current balancing scheme. The PWM output of the dual phase controller is capable of operating at a switching frequency of up to 2MHz with a relative phase adjustment of 180o.
The UCD7230 synchronous buck driver has been designed to work with the UCD9112 controller to provide a highly integrated digital power solution. addition to 4A output drive capability, the driver integrates current limit, short circuit protection as well as under-voltage lockout protection. The UCD7230 also has a 3.3V, 10mA linear regulator that provides the supply current for the controller.
