SLUUCK5 November 2021 TPS92623-Q1
Table 3-1 shows the typical parameters for the TPS92623-Q1EVM. The typical input voltage range is from 9 V to 20 V. The full-scale output current of the TPS92623-Q1EVM is 150 mA per channel. Users can adjust the output current by changing the sensing resistor (Rsns).
| Parameters | Value |
|---|---|
| Input voltage (V) | typical: 9-20 |
| Output current per channel (mA) | 130 |
| LED per channel | 3s1p LED string |
| Rsns (Ω) | 1.15 |
| Rres (Ω) | 86.4 |
Follow these steps for the EVM test setup:
Set the voltage of the dc power supply to 12 V and set the current limit to 1 A.
Connect the positive and negative outputs of the power supply to connectors VBAT and GND respectively on the EVM board.
With the default jumper connections, the board must begin operating after the power supply is turned on. Modify the jumpers for other operating modes.
