Description

PMP9476 is non-sync buck converter plus a non-sync boost controller accepts an input voltage of 3.5V to 40V, and outputs 5V, capable of providing 3A of current to the load.

Features
  • Small form factor Start Stop Supply
  • Class 5 CISPR 25 Conducted EMI compliant
  • Reverse Polarity Protection Built In
  • Single rectifier system, eliminated the boost high side rectifier with PFET
  • PFET to replace LM3481 controller rectifier to improve efficiency and thermal performance
  • Low Component Temperature Rise
