SLVUBV4A December 2020 – December 2021 TPS272C45
Table 5-1 shows the test points populated on the board as well as the signal connectors.
| Connector and Test Point | Description |
|---|---|
| J1 to J4 | BOOST-XL headers to connect to Texas Instruments LaunchPad Ecosystem |
| J5, TP1 | Supply voltage |
| J6 | Supply rail for Vdd (A, C, D version of the TPS272C45 only) |
| J7, J22, TP4, TP5, TP6 | Ground connections |
| TP7 | Current sense output (SNS) |
| J20, TP3 | Output voltage 2 (VOUT2) |
| J21, TP2 | Output voltage 1 (VOUT1) |
| TP8 | Enable for VOUT1 (EN1) |
| TP9 | Enable for VOUT2 (EN2) |
| TP10 | Shared fault line (FAULT) |
| TP11 | IC Ground (IC_GND) |
Table 5-2 shows the relevant configuration jumpers of the TPS272C45EVM as well as the associated values. Please refer to the TPS272C45 data sheet for detailed information on each pin's functionality.
| Jumper | Function/Settings |
|---|---|
| J8 | Controls EN1 and enables, disables VOUT1 |
| J9 | Controls EN1 and enables, disables VOUT2 |
| J10 | Sets DIA_EN and enables, disables diagnostics |
| J11 | Controls the SEL pin to set which diagnostics are reported by the SNS pin |
| J12 | Sets the functionality of the device during fault conditions via the LATCH pin |
| J13 | Enables, disables the on-board 3.3-V LDO. Must be set to top position (marked on silk screen as 3.3-V LDO) to allow J8 to J12 to be high. |
| J14, J15 | Controls which resistance value that is going into ILIM1. Only populate either J14 or J15 (not both) at a time. If J14 is populated a 10-kΩ value is used and if J15 is used a 4.99-kΩ value is used for ILIM1. If controlling from a from a microcontroller do not populate J14 or J15. |
| J16 | Controls whether or not to use the diode/resistor ground network for reverse current blocking. Populate jumper to bypass ground network. |
| J17 | Selects if Vdd is being supplied by the BoosterPack or the on-board LDO. Do no populate if being supplied externally through J6. |
| J18 | Controls if the FAULT line is being pulled up by the BoosterPack or the on-board LDO |
| J19 | Connects the BoosterPack 3.3-V rail to the on-board LDO's 3.3-V output giving the ability to power the connected LaunchPad from the LDO. |

Configures pin 18 to be connected to ILIMD in A, B, C version or FLT1 in D version |
