TPSM83102EVM-125 Evaluation Module
Description
The TPSM83102EVM-125 evaluation module is
designed to help users easily evaluate and test the
operation and functionality of the TPSM83102 and
TPSM83103 buck-boost converter family. The EVM
has the output voltage set to 3.3V . The output voltage
can be programmed via I
and 5.5V. The EVM operates with an input voltage
between 1.6V and 5.5V and the output current can go
up to 1.5A when Vin≥2.7V.
