TPS65291 EVM User's Guide
NOTE: Banana jacks and screw terminals allow two different connection options for providing power
to or delivering power from the input and output pins of the TPS65291. For each power
connection, use either banana plugs or screwed-in wires; do not use both.
Figure 3 shows the test setup for applying power to both B1_VIN (J1) and B2_VIN (J2) on the
TPS65291EVM from a single power supply and measuring the output voltage B2_VOUT (J6) when power
is first applied.
Figure 3. TPS65291 Test Setup: Power Supply and Multi-meter Connections
J1 (B1_VIN) and J9 (GND), or J4 (pin 2 = B1_VIN, pin 1 = GND) — TheJ1 and J9 banana jacks and the
J4 screw terminal are for providing power to BUCK1 through the positive lead (+) of a power supply
and a return path to ground through the negative lead (–).
J2 (B2_VIN) and J9 (GND), or J5 (pin 1 = B2_VIN, pin 2 = GND) — TheJ2 and J9 banana jacks and the
J5 screw terminal are for providing power to BUCK2.
J6 (B2_VOUT) and J12 (GND), or J10 (pin 2 = B2_VOUT, pin 1 = GND) — TheJ6 and J12 banana
jacks and the J10 screw terminal are for attaching a load to draw power from BUCK2.
J11 (LDO_SW_VOUT) and J12 (GND), or J13 (pin 1 = LDO_SW_VOUT, pin 1 = GND) — TheJ11 and
J12 banana jacks and the J13 screw terminal are for attaching a load to draw power from
LDO_SW.
