The H-Bridge architecture is among the most efficient buck-boost topology for high current applications. The device can work in current mode (E.G. LED driver, battery charger) or as a voltage regulator. Capable to drive multiple LED functions (E.G. LB, HB, DRL) with a single DC-DC converter for a more compact and efficient design.

Features

  • High Power Direct Buck boost controller
  • SPI interface: diagnostics and control
  • Spread Spectrum for improved EMC
  • multi-load single inductor applications
  • High efficiency (up to 95%)
  • Limp Home function uC Less operation
  • Output: 2V-55V Input: 4.5V-40V
