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.
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
for
TPS65023B and
for TPS650231 - defaults LDO output voltages.)
JP9 – DEFLDO2
Sets default voltage for LDO1 and LDO2 in combination with DEFLDO1. (See
for
TPS65023B and
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.
