Product InformationFeatures
All other trademarks are the property of their respective owners. DESCRIPTION/ORDERING INFORMATIONThe UCD9112 is a dual-phase synchronous buck digital PWM controller designed for point of load power applications. This device integrates dedicated circuitry for DC/DC loop management with a microcontroller core, flash memory and a PMBus™ interface to support configurability, monitoring and management of a point of load. The UCD9112 is capable of operating at switching frequencies of up to 1MHz. The UCD9112 evaluation module comes with the Fusion Digital Power Designer graphical user interface (GUI). This GUI allows the designer to configure the operating parameters and loop response of the power supply controller. This configuration can then be stored to the devices on chip non-volatile memory. This will enable a synchronous buck hardware design to be dynamically calibrated and reconfigured to optimize a single hardware design for a variety of applications. The UCD7230 synchronous buck driver has been designed to work with the UCD9112 controller to provide a highly integrated digital power solution. In 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. |
