Description

The reference design shows the wide input voltage capability, simple layout, and small solution size of the LMR14050 SIMPLE SWITCHER® Buck Converter and the LMZ20502 Nano Module. The LMR14050 provides a 5V output rail which feeds into two LMZ20502 Nano Modules.  The modules provide a 3.3V and a 1.8V rail.  The 5V, the 3.3V, and the 1.8V rails are capable of delivering a maximum of 2A load at their respective output voltages.

Features
  • Wide Input Voltage Range
  • Easy to Use
  • Small Solution Size
  • Modular Design
