4 TPS1HA08x EVM Assembly Drawings and Layout
Figure 2 through Figure 4 show the design of the TPS1HA08x PCB. The EVM was designed using FR4
material on a four-layer (2s2p) board. All components are located in an active area on the top side and
active traces are provided in the top and bottom layers to allow the user to easily view, probe, and
evaluate. Moving components to both sides of the PCB can offer additional size reduction for space-
constrained systems.

5 Current Limit
When IOUT reaches the current limit threshold, ICL, the device can switch off immediately (versions A, B,
and E), or the device can remain enabled and limit IOUT (versions C and D). The TPS1HA08-Q1 will be
available in multiple variants which collectively allow both of these behavior options. In the case that the
device remains enabled (and limits IOUT), the thermal shutdown or energy limit protection feature may be
triggered due to the high amount of power dissipation in the device.
6 Current Sense
High-accuracy current sensing allows real-time monitoring and more diagnostics without further
calibration. A current mirror is used to source a 1/4600 of the load current on SNS pin. The 1-kΩR10
resistor is connected to the SNS pin to convert the current source into a voltage:
VSNS = 1000 × IOUT / 4600

field representative prior to connecting interface electronics including input power and intended loads. Any loads applied
outside of the specified output range may also result in unintended and/or inaccurate operation and/or possible
permanent damage to the EVM and/or interface electronics. Please consult the EVM user guide prior to connecting any
load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative.
During normal operation, even with the inputs and outputs kept within the specified allowable ranges, some circuit
components may have elevated case temperatures. These components include but are not limited to linear regulators,
switching transistors, pass transistors, current sense resistors, and heat sinks, which can be identified using the
information in the associated documentation. When working with the EVM, please be aware that the EVM may become
very warm.
