Description

The PMP10928 reference design uses the TPS5402 non-synchronous Buck controller along with INA213 current shunt monitor to achieve CC/CV control for an 1.5V/1.5A output from 6-12V input voltage.  +/-5% voltage regulation in CV mode and +/-5% in CC mode is achieved in this design. It is notable that this design allow the output voltage as low as 0.4V in CC mode.

Features
  • 6-12V input to 1.5V/1.5A output with CC/CV controls
  • +/-5% voltage regulation in CV mode
  • +/-5% current regulation in CC mode
  • Allow as low as 0.4V output voltage in CC mode
  • 1.65" x 1.8" board dimension
  • Test report is available
