INPUT / OUTPUT | DESCRIPTION |
J11 – GND | Return for VDCDC1 |
J12 – VDCDC2 | Output from DCDC2 switching regulator, maximum output current 1 A, default voltage setting 2.5 V. |
J13 – GND | Return for VDCDC2 |
J14 – VLDO1 | Output from the low drop out regulator VLDO1, maximun current out is 50 mA, default value 1.1 V. |
J15 – GND | Return for VLDO1 |
J16 | Output from the low drop out regulator, VLDO2 maximum current out is 50 mA, default value 1.3 V. |
J17 – GND | Return for VLDO2 |
J18 – VDCDC3 | Output from the switching regulator DCDC3, maximum current is 800 mA, default value 1.55 A |
J19 – GND | Return for VDCDC3 |
J20 – USB | USB interface connector |
JP1 – DEF 1 | Sets voltage for DCDC1 to 3 V or 3.3 V. |
JP2 – DEF 2 | Sets voltage for DCDC2 to 2.5 V or 1.8 V. |
JP3 – DEF 3 | Sets voltage for DCDC3 to 1.55 V or 1.3 V. |
JP4 – DCDC1 ON/OFF | EN for regulator DCDC1, default setting is ON. |
JP5 – DCDC2 ON/OFF | EN for regulator DCDC2, default setting is ON. |
JP6 – DCDC3 ON/OFF | EN for regulator DCDC3, default setting is ON. |
JP7 – LDO ON/OFF | EN for both LDO1 and LDO2 regulators, default setting is ON. |
S1 – GPIO1 | S1 is a normally open momentary |
The GPIO1 input is configured on the TPS65020 as a debounced push button that drives an | |
| ON/OFF circuit with output at GPIO2. |
| S2 is a normally open momentary |
S2 – HOT_RST | input of the TPS65020 to GND generating the Hot_Reset pulse. The HOT_RST pin is externally |
| pulled up. |
2.2Setup
The following steps must be followed before the EVM is operated
1.Install the TPS65020EVM Software.
2.Connect input voltages and loads to the EVM.
3.Configure all EVM jumpers to factory setting.

4.Connect the Molex cable between the EVM and the EV2300. Note that the Molex cable must connect to the I2C connector on the EV2300.
5.Connect the USB cable between the computer and the EVM.
6.Turn on all supplies and loads.
7.Run the TPS65020EVM software.
