1 Introduction
The TPS563231 is a single, adaptive on-time, D-CAP3™ mode, synchronous buck converter requiring a
very low external component count. The D-CAP3 control circuit is optimized for low-ESR output capacitors
such as POSCAP, SP-CAP, or ceramic types and features fast transient response with no external
compensation. The switching frequency is internally set at a nominal 600 kHz and enters Advanced Eco-
mode in light load conditions. The high-side and low-side switching MOSFETs are incorporated inside the
TPS563231 package along with the gate-drive circuitry. The low drain-to-source on resistance of the
MOSFETs allows the TPS563231 to achieve high efficiencies and helps keep the junction temperature low
at high output currents. The TPS563231 dc/dc synchronous converter is designed to provide up to a 3-A
output from an input voltage source of 4.5 V to 17 V. The output voltage range is from 0.6 V to 7 V. Rated
input voltage and output current ranges for the evaluation module are given in Table 1.
The TPS563231EVM-032 evaluation module (EVM) is a single, synchronous buck converter providing 3.3
V at 3 A from 4.5-V to 17-V input. This user’s guide describes the TPS563231EVM-032 performance.

3 Modifications
These evaluation modules are designed to provide access to the features of the TPS563231. Some
modifications can be made to this module.
3.1 Output Voltage Setpoint
To change the output voltage of the EVMs, it is necessary to change the value of resistor R5. Changing
the value of R5 can change the output voltage above 0.6 V. The value of R5 for a specific output voltage
can be calculated using Equation 1.
(1)
Table 3 lists the R5 values for some common output voltages. Note that the values given in Table 3 are
standard values and not the exact value calculated using Table 3.
