TPS56628EVM-534, 6-A Regulator Evaluation Module
This user's guide contains information for the TPS56628EVM-534 evaluation module (EVM) as well as for
the TPS56628. Included are the performance specifications, schematic, and the bill of materials of the
TPS56628EVM-534.
1 Introduction
The TPS56628 is a single, adaptive on-time, D-CAP2™-mode, synchronous buck converter requiring a
low external component count. The D-CAP2 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 650 kHz. Pulse skipping Eco-mode™
operation improves efficiency under light load conditions. The high-side and low-side switching MOSFETs
are incorporated inside the TPS56628 package along with the gate-drive circuitry. The low drain-to-source
on-resistance of the MOSFETs allows the TPS56628 to achieve high efficiencies and helps keep the
junction temperature low at high-output currents. The TPS56628 dc/dc synchronous converter is designed
to provide up to a 6-A output from an input voltage source of 4.5 V to 18 V. The output voltage range is
from 0.6 to 5.5 V. Rated input voltage and output current range for the evaluation module are given in
Table 1.
The TPS56628EVM-534 evaluation module circuit is a single, synchronous buck converter providing 1.05
V at 6 A, from 4.5-V to 18-V input. This user’s guide describes the TPS56628EVM-534 performance.

Modifications
3 Modifications
These evaluation modules are designed to provide access to the features of the TPS56628. Some
modifications can be made to this module.
3.1 Output Voltage Setpoint
To change the output voltage of the EVMs, change the value of resistor R1. Changing the value of R1 can
change the output voltage more than 0.8 V. The value of R1 for a specific output voltage can be
calculated using Equation 1.
For output voltage from 0.8 to 5.5 V:
(1)
Table 3 lists the R1 values for some common output voltages. An option feed-forward capacitor (C4) may
be used to improve phase margin. Pads for this component (C4) are provided on the printed-circuit board
(PCB). Note that the resistor values given in Table 3 are standard values and not the exact value
calculated using Equation 1.

3.2 Output Filter and Closed-Loop Response
The TPS56628 relies on the output filter characteristics to ensure stability of the control loop. Table 3
shows the recommended output filter components for common output voltages. It is possible for other
output filter component values to provide acceptable closed-loop characteristics. R3 and TP4 are provided
for convenience in breaking the control loop and measuring the closed-loop response.
