3.2.10 PMBUS1, PMBUS Connector for Smart Reflex Control
The TMS320C6657 DSP core power is supplied by a Smart-Reflex power controller UCD9222 with the Integrated
FET Driver UCD7242. PMBUS1 provides a connection between UCD9222 and remote connection during
development. Through the USB to GPIO pod provided by TI, the user can trace and configure the parameters in
UCD9222 with the Smart-Fusion GUI. The pin out of PMBUS1 is shown in table below.
