2.1 Jumper Information

Table 3-1 shows the relevant configuration jumpers of the TPS274C65CPEVM as well as the associated values. Please refer to the TPS274C65CP data sheet for detailed information on the functionality of each pin.

Note: If the ground network is used (J12 unpopulated), then an external VDD needs to be used at a voltage greater than 4 V due to the ground shift and minimum VDD undervoltage lockout threshold.
Note: Please note that a white mark on the jumper silkscreen is reflecting the position 1 of the jumper.
Table 2-1 Jumper Configurations
JumperFunction/Settings
J10Connect to pull the REG_EN signal low.
J11Connect to use the external 3.3V rail generated by the on-board buck converter to power the VDD of the device. Connecting this jumper lowers the quiescent current used by the device in comparison to when the internal VDD is used.
J12

Connect to override.

the ground network and connect IC ground to module ground.

J13Connect 1 and 2 to power EN1 with VDD Connect 2 and 3 to pull EN1 low.
J14Connect 1 and 2 to power EN2 with VDD Connect 2 and 3 to pull EN2 low.
J15Connect 1 and 2 to power EN3 with VDD Connect 2 and 3 to pull EN3 low.
J16Connect 1 and 2 to power EN4 with VDD Connect 2 and 3 to pull EN4 low.
J17Connect 1 and 2 to pull LATCH HI to configure the device in latch (on fault) mode Connect 2 and 3 to pull LATCH LO to configure device in auto-retry on fault.
J18

Connect 1 and 2 to pull DIAG_EN HI to enable diagnostic reporting Connect 2 and 3 to disable.

Diagnostic reporting.
