Introduction
The Texas Instruments TPS62230EVM-370 evaluation module helps designers evaluate the operation
and performance of the TPS62230 family of devices. These devices are high-efficiency, ultra-small size,
buck converters that switch at 3 MHz.
The EVM contains three independent dc/dc converters. Table 1 lists the default output voltages of the
converters.

Setup
This section describes the jumpers and connectors on the EVM and how to properly connect, set up, and
use the TPS62230EVM-370.
Input/Output Connector Descriptions
J11 , J21, and J31 – VIN
This is the positive input connection to the corresponding converter. Twist the leads to the input supply,
and keep as short as possible to minimize EMI transmission.
J13 , J23, and J33 – GND
This is the return connection for the input power supply for the corresponding converter.
J12, J22, and J32 – Input Sense
This connection provides monitoring for input voltage using independent traces to the input capacitor.
J14, J24, and J34 – VOUT
This is the positive connection from the output of the corresponding buck power supply.
J16 , J26, and J36 – GND
This is the negative connection from the output of the corresponding buck power supply.
J15, J25, and J35 – Output Sense
This connection provides monitoring for output voltage using independent traces to the output capacitor.
JP11, JP21, JP31 – ENABLE
This jumper enables or disables the converter through the IC EN pin. Connect the shorting jumper from
the center (EN) pin to either the ON or OFF position. Never leave EN floating.
