Introduction
The Texas Instruments TPS7A6201QKTT EVM evaluation module (EVM) helps designers evaluate the
operation and performance of the TPS7A6201QKTT Linear Regulator.

Input/Output Connector Description
VBAT is the protected power input for the regulator. The test point provides a power (Vbat) connection
and a reverse battery protection diode to allow the user to power the EVM.

GND is the ground return for the regulator. The EVM provides three GND test points to allow the user to
power the EVM, connect the load and attach an oscilloscope ground lead

battery protection diode. The user can also apply power to the regulator through this test point.
VOUT is output for the regulator. The test point provides a connection to attach a load to the EVM.
EN is a test point to monitor the Enable input to the device. It can also be used to provide an enable signal
to the device from an outside source, if the EN jumper is left open. The EN jumper will disable the
regulator when removed and enable the regulator when installed.

FB is a test point to monitor the feedback voltage to the device. The EVM is setup to provide a 5V output
voltage, but the feedback resistors can be changed to set the output voltage to a value between 2.5V and
7V using the equation presented in

2.2
Setup
The input voltage range for the converter is (VOUT + 0.3V) volts to 40 volts. The EVM can support up to
300mA of load current.
300mA of load current.
2.3
Operation
The TPS7A6201QKTT will power-up after the VBAT voltage has exceeded the Power-On Reset threshold.
In this configuration, the device will power up when power is applied.
The PCB offers footprints for the TPS7A6201QKTTQ1 or the TPS7A6201QKVUQ1 device.
