Product Details

The MAX20040 evaluation kit (EV kit) is a fully assembled and tested application circuit for the MAX20040, which is a small, synchronous buck-boost converter family with integrated high-side and low-side switches. Each EV kit is designed to deliver up to 1.2A with input voltages from +4.5V to +36V, while using only 52µA quiescent current at no load. Input voltage can be lowered to +2V after regulation. Output-voltage quality can be monitored by observing the PGOOD signal.

Applications

  • Body Electronics
  • Infotainment Systems
  • Point-of-Load Power Supply
  • Power over Coax
  • Start-Stop Systems
