Connector and Test Point Descriptions
4.1
Enable Jumpers/Switches: TPS62060EVM
4.1.1
J1 – VIN
This header is the positive connection to the input power supply. The power supply must be connected
between J1 and J3 (GND). Twist the leads to the input supply, and keep them as short as possible. The
input voltage must be between 2.7 V and 6 V.

4.1.2
J2 – S+/S–
J2 S+/S– are the sense connections for the input of the converter. Connect a voltmeter, or the sense
connection of a power supply or oscilloscope, to this header.

4.1.3
J3 – GND
This header is the return connection to the input power supply. Connect the power supply between J3 and
J1 (VIN). Twist the leads to the input supply, and keep them as short as possible. The input voltage must
be between 2.7 V and 6 V.

4.1.4
J4 – VOUT
This header is the positive output of the step-down converter. The output voltage of the TPS62060 is
adjustable with feedback resistors R1 and R2. On the EVM, the output voltage is set to 1.8 V by default.

detailed information.
4.1.5
J5 – S+/S–
J5 S+/S– are the sense connections for the output of the converter. Connect a voltmeter, or the sense
connection of an electronic load or oscilloscope, to this header.
connection of an electronic load or oscilloscope, to this header.
4.1.6
J6 – GND
J6 is the return connection of the converter. A load can be connected between J6 and J4 (V
OUT
). The
converter is capable of carrying a load current up to 1600 mA.
4.1.7
JP1 – EN
This jumper enables/disables the TPS62060 on the EVM. Shorting jumper JP1 between the center pin
and On turns on the unit. Shorting the jumper between center pin and Off turns off the unit. A 1-M
and On turns on the unit. Shorting the jumper between center pin and Off turns off the unit. A 1-M
Ω
pullup
resistor is connected between VIN and EN. Removing jumper JP1 turns on the converter.
4.1.8
JP2 – MODE
This jumper enables/disables the power-saving mode under light loads. Shorting jumper JP2 between the
center pin and PWM disables the power-saving mode. If the power-save mode is disabled, the converter
operates in forced PWM mode over the entire load current range. Shorting the jumper between the center
pin and PFM enables the power-saving mode. The device operates in power-saving mode under light load
conditions. See the TPS62060 data sheet (

pulldown resistor is connected between GND and MODE. By removing JP2, the converter operates
in power-saving mode under light-load conditions.
