DESCRIPTION
The UCD9111 is single 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 UCD9111 is
able to monitor power supply operating conditions
and report the status to the host system through
PMBus. The monitoring parameters are configurable
through GUI. The GUI also allows the power supply
designer to easily to configure the digital control loop
characteristics and generate the loop gain bode plot.
The UCD7230 synchronous buck driver has been
designed to work with the UCD911x 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
.
