4 Connection Descriptions

Most connectors and test points are labeled with their functional names on the silk screen of the PCB and the actual component names are omitted to avoid clutter on the silk screen of the EVM. Likewise, jumpers are labeled to be self explanatory. The following tables contain a description of each test point and its purpose.

Note that by default the TPS1HC30EVM comes configured for standalone operation with no attached LaunchPad development kit.

Table 4-1 Connections and Test Points
Connector or Test PointDescription
J5, VBB test pointsVBB input (supply)

J7, VOUT test points

VOUT output (from device)

J6, J8, GND test pointsGround connection (system ground)
DIAG_ENEnable and disable diagnostics on the TPS1HC30-Q1
ENEnable line for the TPS1HC30-Q1
LATCHControls latch functionality for the TPS1HC30-Q1
SNSCurrent sense test point for the current sense output of the TPS1HC30-Q1
FAULTOpen-drain fault test point for the TPS1HC30-Q1. Pullup source can be configured using J13.

Table 4-2 Jumper Configurations
JumperFunction, Setting
Current limit settingPOT enables the physical "Current Limit" potentiometer, DIGI POT enables the digital potentiometer U3 (TPL0102-100), not populating the jumper defaults to the solder down resistor pad, R4.
SNS pot enableEnables the physical "SNS" potentiometer connected to the current sense output of the TPS1HC30-Q1. Not populating this jumper defaults to the solder down resistor, R12.
LDO_EN / LDO_DISEnables and disables the onboard 3.3-V LDO
J13 (fault pullup)Configures where the fault pin is pulled up from. This jumper is either from the 3.3-V LDO or the 3.3-V rail from the attached LaunchPad development kit.
LDO to BP powerConnects the output of the onboard 3.3-V LDO to the 3.3-V rail of the attached BoosterPack plug-in module. This jumper is used to power the attached LaunchPad development kit using the LDO of the TPS1HC30EVM.
DIAG_ENConnects the TPS1HC30-Q1's DIAG_EN signal to either the LDO's 3.3-V signal or ground
ENConnects the TPS1HC30-Q1's EN signal to either the LDO's 3.3-V signal or ground
LATCHConnects the TPS1HC30-Q1's LATCH signal to either the LDO's 3.3-V signal or ground
GND net bypassBypasses the resistor and diode ground network and connects IC ground to system ground
