K2G General Purpose Evaluation Module (EVMK2G)
4 Power Supply
NOTE: Always use the power supply (CUI, Inc., part number SDI65-12-U-P5) or an equivalent
12V/5A model with the applicable regional product regulatory/safety certification standards
such as (by example) UL, CSA, VDE, CCC, PSE, and so on.
The EVMK2G can be powered from a 12V/5.0A DC (60W) external power supply connected to the
DC power jack (J3). Internally, +12V input is converted into required voltage levels using local DC-DC
converters. The regulators used in the EVM are listed in
Table 15 .

The power requirements of the processor are met by the TPS659118 (U32) Power Management IC
(PMIC). The generation and sequencing requirements of various powers to the 66AK2Gxx processor are
also handled by the TPS659118. The TPS659118 is controlled by the I2C0 interface of the 66AK2Gxx.
