UCD9112 Description
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 pensator is configurable with the GUI to meet dynamic converter performance allowing a single hardware design to cover a broad range of POL applications.
