Description
-----------
[From datasheets] UCD9220, UCD9222, UCD9224, UCD9240, UCD9244, UCD9246, and
UCD9248 are multi-rail, multi-phase synchronous buck digital PWM controllers
designed for non-isolated DC/DC power applications. The devices integrate
dedicated circuitry for DC/DC loop management with flash memory and a serial
interface to support configuration, monitoring and management.
This driver is a client driver to the core PMBus driver. Please see
