Texas Instruments TPS1HC30-Q1, User Manual

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.
Table 4-1. Connections and Test Points
Connector or Test Point Description
J5, VBB test points VBB input (supply)
J7, VOUT test points VOUT output (from device)
J6, J8, GND test points Ground connection (system ground)
DIAG_EN Enable and disable diagnostics on the TPS1HC30-Q1
EN Enable line for the TPS1HC30-Q1
LATCH Controls latch functionality for the TPS1HC30-Q1
SNS
Current sense test point for the current sense output of the
TPS1HC30-Q1
FAULT
Open-drain fault test point for the TPS1HC30-Q1. Pullup source can
be configured using
J13 .
Table 4-2. Jumper Configurations
Jumper Function, Setting
Current limit setting
POT 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 enable
Enables 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_DIS Enables 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.
LDO to BP power
Connects the output of the onboard 3.3-V LDO to the 3.3-V rail of
the attached BoosterPack. This jumper is used to power the attached
LaunchPad using the LDO of the TPS1HC30EVM.
DIAG_EN
Connects the TPS1HC30-Q1's DIAG_EN signal to either the LDO's
3.3-V signal or ground
EN
Connects the TPS1HC30-Q1's EN signal to either the LDO's 3.3-V
signal or ground
LATCH
Connects the TPS1HC30-Q1's LATCH signal to either the LDO's
3.3-V signal or ground
GND net bypass
Bypasses the resistor and diode ground network and connects IC
ground to system ground
