TPS561300 Step-Down Converter Evaluation Module
Description
The TPS561300 evaluation module (EVM) is
a simple, easy-to-use, 1A synchronous step-
down converter in an SOT236 package. The
TPS561300EVM is a fully assembled and tested
circuit for evaluating the TPS561300 step-down
converter. The TPS561300EVM operates from 5V to
30V input, 24V nominal, and provides a 5V output
at 1A. The EVM also includes Alternating Current
(AC) signal injection terminals for feedback loop
measurements.

The TPS561300 is a high efficiency, easy-to-use, synchronous buck converter. With the wide input voltage range of 4.5V to 30V, the TPS561300 is an excellent choice for systems powered from 5V, 12V, 19V, 24V power bus rails. The device supports up to 1A continuous output current. The device employs fixed frequency peak current control mode for fast transient response and good line and load regulation. - Page 3 TP6, TP8, TP12, TP13 GND monitor point TP10 Switch node test point EN test point TP11 Test point for loop response measurements SLUUD95 – FEBRUARY 2025 TPS561300 Step-Down Converter Evaluation Module Submit Document Feedback Copyright © 2025 Texas Instruments Incorporated...
