Overview

PMP10770 incorporates the TPS53219A and CSD87384M, which are the Green alternative to the TPS53355 30A dc/dc converter, and are 100% Pb-free. The design is for 10V-14V input, 1Voutput at 34A current with  83% efficiency at full load.

Features
  • 100% Pb free
  • Green alternative to TPS53355
  • 500KHz switching frequency
  • 83% efficiency at full load of 34A
  • Design length of 50mm
  • 15.4mV output voltage ripple at 12VIN, and full load
