Test Setup
2-3 EVM Operation
2.2 Test Setup
Although the absolute maximum voltage for V
IN
is 6 V, the TPS6512x family
is designed to operate with input voltages of 5.5 V or less. For best results with
the EVM as packaged, connect a power supply with a 3.3-V output voltage and
current limit set to at least 500 mA.
To enable the TPS65120EVM, first short pins 1−2 of jumper JP2 (tie RUN to
ON); then short pins 1−2 of jumper JP1 (tie EN to ON).
To enable the TPS65124EVM, first short pins 1−2 of jumper JP2 (tie RUN to
ON); then short pins 1−2 of jumper JP1 (tie EN to ON) then short pins 1−2 of
jumper JP5 and JP6 in any order to enable VGL and VGH, respectively.
Connect output loads on each rail not to exceed the maximum current ratings
in Table 1−1.
