Description

PMP10035 is a sycnchronous buck converter with 48V input voltage and 31V output voltage. Due to ceramic capacitors only this design is suitable for automotive applications (48V bus). With  switching frequency of 400kHz, the efficiency is higher than 96% at full load.

Features
  • Small outline (21.6mm x 33.4mm)
  • Ceramic capacitors only
  • Low temparature rise at full load
  • 48V input
  • 31V output @ 1.3A
