TPS562243 and TPS562246 Step-Down Converter
Evaluation Modules
Description
The TPS56224x is a single, D-CAP3
mode, synchronous buck converter with input voltage
ranging from 4.2V to 17V and supports up to 2A
continuous current. The device is optimized to operate
with minimum external component counts and low
standby current. The TPS562243 operates in Eco-
mode and the TPS562246 operates in FCCM mode.
The TPS56224xEVM is a fully assembled and tested
circuit for evaluating the TPS56224x converter.

    4-3, and Figure 4-4 show the board layout for the TPS562243EVM. The top layer contains the main power traces for VIN, VOUT, and ground. Connections for the pins of the TPS562243 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.
