1 Introduction

The Texas Instruments TPS7A6050QKTT EVM evaluation module (EVM) helps designers evaluate the

operation and performance of the TPS7A6050QKTT Linear Regulator.

The EVM contains one Linear Regulator (see Table 1).

2 Setup

This section describes the jumpers and connectors on the EVM as well and how to properly connect, set

up and use the TPS7A6050QKTT EVM.

2.1 Input/Output Connector Descriptions

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.

VIN is a power test point. The test point allows the user to measure the input voltage after the reverse

battery protection diode. The user can also apply power to the regulator through this test point.

VOUT is power output for the regulator. The test point provides a connection to attach a load to the EVM.

DLY is a test point to monitor the charging of the delay capacitor.

nRST is a test point to monitor the reset flag. The reset flag is an active low, open drain output that will

remain low when the output voltage is below the power-on reset threshold of approximately 4.65 V.

DELAY is the jumper used to set the delay time to hold the nRST pin low after the supply has exceeded

the programmed power-on reset threshold voltage of approximately 4.65 V. The jumper capacitors allow

the reset delay to be set to four set points. The user can set a specific delay time by changing one of the

delay capacitors – C5, C6 or C7. The capacitor value can be set using this equation.

2.2 Setup

The input voltage range for the converter is 5.3 V to 40 V. The EVM can support up to 300 mA of load

current.
