Introduction
1 Introduction
The TPS562242 is a single, adaptive on-time, D-CAP3™ control mode, synchronous buck converter that
requires a very low external component count. The D-CAP3 control mode 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 1.4 MHz and enters Eco-mode in light load
conditions. The high-side and low-side switching MOSFETs are incorporated inside the TPS562242 package
along with the gate-drive circuitry. The TPS562242 DC/DC synchronous converter is designed to support up to a
2-A continuous current from an input voltage source of 3 V to 17 V. The output voltage range is from 0.8 V to 10
V. Rated input voltage and output current ranges for the evaluation module are given in Table 1-1.
The TPS562242EVM evaluation module (EVM) is a single, synchronous buck converter providing 1.05 V at 2 A
from 3-V to 17-V input. This user’s guide describes the TPS562242EVM performance.

3 Output Voltage Setpoint
The output voltage of the EVM can be selected by changing the value of resistor R4 (RFBT) and R5 (RFBB). TI
recommends using 1% tolerance or better divider resistors. Start with a 10 kΩ for R5 (RFBB) and use Equation 1
to calculate R4 (RFBT). To improve efficiency at light loads, consider using larger value resistors. If the values are
too high, the regulator is more susceptible to noise and voltage errors from the FB input current are noticeable.

4.1 Input and Output Connections
The TPS562242EVM is provided with input and output connectors and test points as shown in Table 4-1. Figure
4-1 shows connectors and jumpers placement on TPS562242EVM board.
A power supply capable of supplying 2 A must be connected to J1 through a pair of 20-AWG wires. The load
must be connected to J2 through a pair of 20-AWG wires. The maximum load current capability is 2 A. Wire
lengths must be minimized to reduce losses in the wires. Test point TP2 provides a place to monitor the VIN input
voltages with TP6 providing a convenient ground reference. TP3 is used to monitor the output voltage with TP10
as the ground reference.

This section provides a description of the TPS562242EVM, board layout, and layer illustrations.
5.1 Layout
Figure 5-1, Figure 5-2, and Figure 5-3 show the board layout for the TPS562242EVM. The top layer contains
the main power traces for VIN, VOUT, and ground. Connections for the pins of the TPS562242 and a large
area filled with ground are also on the top layer. Most of the signal traces are also located on the top side. The
input decoupling capacitors C1, C2, and C3 are located as close to the IC as possible. The input and output
connectors, test points, and all of the components are located on the top side. The bottom layer is a ground
plane along with the signal ground copper fill and the feedback trace from the point of regulation to the top of the
resistor divider network. Both the top layer and bottom layer use 2-oz copper thickness.
Figure 5-4 and Figure 5-5 are the TPS562242EVM board top view and bottom view, respectively.

Concerning EVMs Including Detachable Antennas:
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser)
gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type
and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for
successful communication. This radio transmitter has been approved by Industry Canada to operate with the antenna types
listed in the user guide with the maximum permissible gain and required antenna impedance for each antenna type indicated.
Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited
for use with this device.
