Product Overview

The LM27342MYEVAL evaluation board is used to evaluate the features of LM27342 in 10pin eMSOP packages. This board is designed with a fully functional regulator design which can be synchronised to an external clock between 1000kHz and 2350kHz. The evaluation board provides 3.3V output with 2A current capability. Without an external synchronisation signal, the design operates at 2000kHz reducing the solution size and keeping switching noise out of the AM radio band. The printed circuit board consists of four layers of copper on FR4 material. There is a ground plane on the internal layer directly beneath the LM27342 and a ground plane on the bottom layer. The LM27342 is thermally tied to the ground planes by thermal vias directly underneath the device. The second internal layer is tied half to VIN and half to VOUT.
  • Wide input voltage range from 5V to 20V
  • 2A maximum output current
  • 2MHz high switching frequency
  • 150mΩ NMOS switch with internal bootstrap supply
  • 70nA shutdown current
  • The printed circuit board consists of four layers of copper on FR4 material
  • The LM27342 is thermally tied to the ground planes by thermal vias directly underneath the device
