3.1 Differences Between the TPS6594EVM and the TPS6593EVM
The TPS6593EVM does not provide the functional safety features which are found on the TPS6594EVM. Table
3-1 lists the component differences between the EVMs which are related to functional safety.
Table 3-1. Differences Between TPS6594EVM and TPS6593EVM
Part TPS6594EVM TPS6593EVM Description
(1)
D1 Fitted Not Fitted Protection Diode for VSYS_SENSE
Q1 Fitted Not Fitted Protection FET controlled by OVPGDRV
R20 Fitted Not Fitted Current Limiting resistor for VSYS_SENSE
R21 Fitted Not Fitted Current Limiting resistor for VSYS_SENSE
R25 Not Fitted Fitted Connect VSYS and VCCA
R26 Fitted Not Fitted Connect OVPGDRV to Q1
R39 Fitted Not Fitted Connect VSYS_SENSE to VSYS
R35 Fitted Not Fitted Connect EN_DRV to LED indicator D5 through U2
(1) Unless specifically described the features are the same between the TPS6594EVM and the TPS6593EVM.
3.2 Terminal Blocks
The terminal blocks are simple push and release terminals which can accommodate wire sizes up to 14 AWG.
Table 3-2 lists the terminal blocks found around the perimeter of the EVM. J6, VSYS, is the input voltage for all
regulators (BUCK and LDO).

The remaining 5 terminal blocks are the BUCK outputs.
Table 3-2. Terminal Blocks
Terminal Designator Description
VSYS J6 All Regulator Input (PVIN_LDOx, PVIN_Bx), 2.7 V to 5.5 V Range
BUCK1 J1 Buck 1 Output, 3.5 A Capable
BUCK2 J2 Buck 2 Output, 3.5 A Capable
BUCK3 J3 Buck 3 Output, 3.5 A Capable
BUCK4 J4 Buck 4 Output, 4 A (single phase) or 3.5 A Capable
BUCK5 J5 Buck 5 Output, 2 A Capable
