2 Test Setup

Table 10 shows the typical parameters for the TPS92830EVM. The typical requirement for 3s3p red LEDloads is 9 V–16 V, and 85°C is the maximum ambient temperature for the application. The full-scaleoutput current of the TPS92830EVM is 300 mA. Users can adjust the output current by using the analogdimming function or changing the sensing resistors.

Table 10. TPS92830EVM Parameters

Parameter ValueInput voltage 9 V–16 V Typical

Output current 0–300 mALED 3s3p red LED LR H9GP

Maximum ambient temperature 85°C

The TPS92830EVM can support a minimum 5-V input voltage using one LED. The maximum supportedinput voltage is 40 V, but the output current must be controlled and/or the number of LEDs be properlyselected to limit the temperature on the MOSFETs.

Below is the overview of the setup of the TPS92830EVM. Connect the positive and negative outputs of thedc power supply to TP22 (VBAT) and TP23 (GND) on the TPS92830EVM board. Connect J1 on theTPS92830EVM board and J12 on the LED board together with the 5-wire cable.

Figure 3. TPS92830EVM Setup

With the default jumper connections, the board should begin operating as soon as proper voltage isapplied to the input. Modify the jumpers for other operating modes.
