4 / 17 page Test Setup and Results www.ti.com 2 Test Setup and Results This section describes how to properly connect, set up, and use the TPS54519EVM-037 evaluation module. The section also includes test results typical for the evaluation module and covers efficiency, output voltage regulation, load transients, loop response, output ripple, input ripple, and start-up. 2.1 Input/Output Connections The TPS54519EVM-037 is provided with input/output connectors and test points as shown in Table 4. A power supply capable of supplying 3 A must be connected to J1 through a pair of 20 AWG wires. The load must be connected to J4 through a pair of 20 AWG wires. The maximum load current capability must be at least 4 A to use the full capability of this EVM. Wire lengths must be minimized to reduce losses in the wires. Test-point TP1 provides a place to monitor the V IN input voltages with TP2 providing a convenient ground reference. TP6 is used to monitor the output voltage with TP7 as the ground reference. Table 4. EVM Connectors and Test Points Reference Designator Function J1 V IN (see Table 1 for VIN range). 2-pin header to allow connection of an external track in voltage to SS/TR. Use with optional resistor J2 divider of R5 and R6 J3 V OUT, 1.8 V at 5 A maximum JP1 2-pin header for enable. Connect EN to ground to disable, open to enable. JP2 2-pin header for to allow pullup of PWRGD to V IN TP1 V IN test point at VIN connector TP2 GND test point at V IN TP3 Slow-start monitor test point TP4 PH test point TP5 PWRGD test point TP6 GND test point TP7 Test point between voltage divider network and output. Used for loop response measurements. TP8 Output voltage test point at OUT connector TP9 GND test point at OUT connector 4 TPS54519EVM-037, 5-A, SWIFT ™ Regulator— Evaluation Module SLVU523 – September 2011 Submit Documentation Feedback Copyright © 2011, Texas Instruments Incorporated |
