2 / 17 page Setup www.ti.com 2 Setup This section describes the connectors and headers on the EVM as well as how to properly connect, setup and use the TPS7A4700EVM-094. See the Assembly Layer diagram, Figure 5, for the location and orientation of referenced components. 2.1 Input/Output Connector-Headers and Jumper Descriptions • J1 V IN – Positive (+) input power supply voltage test and measurement header • J2 GND – Ground and measurement header • J3 V OUT – Regulator output (up to 1 Amp) • J4 GND – Ground return from the load (up to 1 Amp) • J5 (S+) – V OUT, Kelvin connection VOUT • J5 (S–) – GRD, Kelvin connection Ground • J6 & J7 – Extra GRD connections • J8 – Enable jumper for external resistor divider • J9 – Enable jumper for the TPS7A4700-094 EVM • J10 – Header for selecting the appropriate output voltage NOTE: The positive input lead and ground return lead from the input power supply should be twisted and kept as short as possible to minimize EMI and source inductance. Additional bulk capacitance in the form of a Tantalum cap (47 µF; 35 V) has been added to the EVM at C1 to counter source inductances that may cause ringing on the load transient waveform during higher current transients. This bulk capacitance should not be necessary in a typical application circuit. Output Voltage Set Note: Set the output voltage by connecting J10 header pins, each assigned to a given voltage level, to ground where V OUT = VREF + (Sum of the jumper voltages). J10 header pins are numbered sequentially, odd pins (1, 3, 5...15) ascending leftward of pin 1 on the top row. All odd pins are connected to ground. Each even pin is numbered right to left sequentially (2, 4, 6…16) on the bottom row and each even pin is assigned a unique voltage level. See the pin-to-pin output voltage assignments in Table 1. Table 1. J10 Jumper Voltages V OUT = VREF (1) + Sum of Voltage Levels Voltage Level Voltage Set Pins Ground Pins 100 mV 16 15 200 mV 14 13 400 mV 12 11 800 mV 10 9 1.6 V 8 7 3.2 V 6 5 6.4 V 4 3 6.4 V 2 1 (1) See the data sheet for V REF value. Publication: SBVS204 Example: Set V OUT to 3.0 V by connecting a shorting jumper from pin 8 to pin 7. V OUT = VREF + 1.6 V = 3.0 V 2.2 Soldering Guidelines Any solder rework to modify the EVM for the purpose of repair or other application reasons must be performed using a hot-air system to avoid damaging the integrated circuit (IC). 2 TPS7A4700EVM-094 Evaluation Module SLVU741 – May 2012 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated |
