J17 – VDCDC3

Output from switching regulator DCDC3; maximum output current 1 A.

J18– GND

Return for VDCDC3.

J19 –

J19 is the interface connector for the I2C interface. Connect a 10-pin ribbon cable between J13 and the USB-to-GPIO interface.

JP1 – DEF1

Sets default voltage for DCDC1, 1.2 V or 1.6 V.

JP2 – DEF2

Sets default voltage for DCDC2, 3.3 V or 1.8 V, in TPS65023B (HPA664-001) configuration. In the TPS650231, no default output voltage options are available. In this case, the output voltage is adjustable with an external voltage divider R3, R2. The default setup is 1.2 V in the factory EVM (HPA664-002) configuration. See section x for advanced voltage scaling options..

JP3 – DEF3

Sets default voltage for DCDC3, 3.3 V or 1.8 V.

JP4 – DCDC1 ON/OFF

EN for DCDC1 converter; default setting is ON

JP5 – DCDC2 ON/OFF

EN for DCDC2 converter; default setting is ON.

JP6 – DCDC3 ON/OFF

EN for DCDC3 converter; default setting is ON.

JP7 – LDO ON/OFF

EN for both LDO1 and LDO2 regulators; default setting is ON.

JP8 – DEFLDO1

Sets default voltage for LDO1 and LDO2 in combination with DEFLDO2. (See Table 2 for TPS65023B and Table 3 for TPS650231 - defaults LDO output voltages.)

JP9 – DEFLDO2

Sets default voltage for LDO1 and LDO2 in combination with DEFLDO1. (See Table 2 for TPS65023B and Table 3 for TPS650231 - defaults LDO output voltages.)

S1 – HOT_RST

S1 is a normally open, momentary pushbutton switch that, when pressed, connects the

HOT_RST input of the TPS650231 to GND, generating the HOT_RESET pulse. HOT_RESET pin is pulled up externally.

3.1Setup

The following steps must be followed before the EVM can be operated.

1.Install the TPS65023B/TPS650231EVM software.

2.Connect input voltages and loads to the EVM.

3.Configure all EVM jumpers to factory setting.

JP4–ON JP1–1.6V JP3–1.8V

JP2–1.8V JP5–ON JP6–ON

JP7–ON JP9–High JP8–High
