The EVM provides three GND test points to allow the user to power the EVM, connect the load, and attach an oscilloscope ground lead. J1 is a jumper used for choosing the power applied at the EN pin; having pin 1 and pin 2 connected pulls EN down to GND and disables the device. With pin 2 and pin 3 connected, the voltage at EN equals the input voltage. NC is a redundant pin which one can leave open. TP_EN is a power test point. The test point allows the user to measure the input voltage at the EN pin. The user can also apply power to this test point directly. TP_FB is a power test point. The test point is available in adjustable-version LDO TPS7A6601 only, and allows the user to measure the internal reference voltage. When adjustable-version device TPS7A6601 is soldered on the EVM, the resistor divider on the board sets the output voltage to 1.5 V. TP_PG is a power test point which allows the user to monitor the status of the PG pin. TP_Vin is a power test point. The test point allows the user to measure the input voltage after the reversebattery protection diode. The user can also apply power to the regulator through this test point. TP_Vout is a power test point; this test point allows the user to measure the output voltage at the Vout pin. The user can also attach a load to the EVM through this pin. Vin is the protected power input for the regulator. The test point provides a power (Vin) connection and a reverse-battery protection diode to allow the user to power the EVM. Vout is power output for the regulator. The test point provides a connection to attach a load to the EVM. 1.2 Setup The input voltage range for the converter is 5.5 V to 40 V. The EVM can support up to 150 mA of load current. Setup steps follow: 1. Short pin 2 and pin 3 of J1. 2. Set the input voltage supply voltage to 12 V and set the current limit to 0.8 A. 3. Connect the input power supply positive lead to Vin and the return lead to GND. 4. Apply the load between Vout and GND. 1.3 Operation The TPS7A66xx EVM powers up after the VBAT voltage has exceeded the power-on-reset threshold. The PCB offers a footprint for the TPS7A66xxQDGNRQ1 device. 2 Board Layout Figure 1, Figure 2 and Figure 3 show the board layout for the TPS7A66xx EVM PWB. The large number of vias beneath the device footprint help to enhance thermal performance. The device pins require soldered attachmentz to the copper landing on the PCB for optimal performance. The PCB provides 2-oz. (0.071-mm thick) copper planes on the top and bottom to dissipate heat. 2 TPS7A66xx EVM Evaluation Module (EVM) Copyright © 2013, Texas Instruments Incorporated SLVU905 – May 2013 Submit Documentation Feedback Board Layout www.ti.com Figure 1.
