2.3.1 Input and Output Capacitors
C2 and C3 are provided for additional input capacitors. These capacitors are not required for proper operation
but can be used to reduce the input voltage ripple.
C9 is provided for an additional output capacitor. This capacitor is not required for proper operation but can be
used to reduce the output voltage ripple and to improve the load transient response. The output capacitance
must remain within the recommended range in the device data sheet for proper operation.
2.3.2 Loop Response Measurement
The loop response of the TPS62830xRZEREVM can be measured by cutting the trace parallel to R3 and
assembling a 50-Ω resistor as R3 to inject the measurement signal across.
3 Setup
This section describes how to properly use the TPS62830xRZEREVM.
3.1 Connector Descriptions
J1, Pin 1 and 2 – VIN

3.2 Hardware Setup
To operate the EVM, set jumpers JP1 to the desired positions per
supply to J1, and connect the load to J2.
4 TPS62830xRZEREVM Test Results
The TPS62830xRZEREVM was used to take the data in the TPS62830x data sheet for the QFN package. See
the device data sheet for the performance of this EVM.

The PG output appears on pin 1 of this header with a convenient ground on pin 2.
EN pin jumper. Place the supplied jumper across ON and EN to turn on the IC. Place the jumper
across OFF and EN to turn off the IC.
MODE pin jumper. Place the supplied jumper across VIN and MODE to force the device in fixed
frequency PWM operation at all load currents. Place the jumper across MODE and GND to enable
power save mode.
