LMZ20502 SIMPLE SWITCHER® Evaluation Board
1 Introduction
The LMZ20501/02 nano modules are easy-to-use DC-DC converters optimized for space-constrained
applications. The LMZ20502 is capable of delivering up to 2A with excellent power conversion efficiency,
output voltage accuracy, line and load regulation, and load transient response. The LMZ20501 is a 1.0A
version, that is pin-to-pin compatible with the LMZ20502.
This engineering evaluation board is designed for rapid prototyping with large pads and extra components.
In addition, jumpers are provided to allow the user to enable the converter and select the operating mode.
A jumper for connecting a network analyzer is also provided, to measure regulator loop response. Please
refer to Figure 1 for the schematic of the EVM.
