All trademarks are the property of their respective owners.
1 Introduction
The TPS62933 is a high efficiency, easy-to-use synchronous buck converter. With the wide input voltage range
of 3.8-V to 30-V, it is ideally suited for systems powered from 5-V, 12-V, 19-V, 24-V power-bus rails. It supports
up to 3-A continuous output current, 0.8-V to 22-V output voltage and maximum 98% duty cycle operation. The
device employs fixed frequency peak current control mode for fast transient response and good line & load
regulation. The optimized internal loop compensation eliminates the external compensation components over a
wide range of output voltage and operation frequency. The Pulse Frequency Modulation (PFM) mode maximizes
the light load efficiency. The ULQ™ (Ultra Low Quiescent) feature is extremely beneficial for long battery life
time in low power operation. The switching frequency can be set by the configuration of RT pin in the range of
200-kHz to 2.2-MHz, which allows optimizing system efficiency, filtering size and bandwidth.
The TPS62933EVM evaluation module (EVM) is a single, synchronous buck converter providing 5-V at 3-A
from 5.1-V to 30-V input. This user’s guide describes the TPS62933EVM performance. Rated input voltage and
output current ranges for the evaluation module are given in Table 1-1.

3.1 Output Voltage Setpoint
To change the output voltage of the EVMs, it is necessary to change the value of resistor R4. Changing the
value of R4 can change the output voltage. The value of R4 for a specific output voltage can be calculated using
Equation 1.

4 Test Setup and Results
This section describes how to properly connect, set up, and use the TPS62933EVM. The section also includes
test results typical for the evaluation modules and efficiency, output load regulation, output line regulation, load
transient response, output voltage ripple, input voltage ripple, start-up, and shut-down.
4.1 Input/Output Connections
The TPS62933EVM is provided with input/output connectors and test points as shown in Table 4-1. Figure 4-1
shows connectors and jumpers placement on TPS62933EVM board.
A power supply capable of supplying 3-A must be connected to J2 through a pair of 20-AWG wires. The load
must be connected to J1 through a pair of 20-AWG wires. The maximum load current capability is 3-A. Wire
lengths must be minimized to reduce losses in the wires. Test point TP3 provides a place to monitor the VIN input
voltages with TP7 providing a convenient ground reference. TP1 is used to monitor the output voltage with TP9
as the ground reference.
