Smart Terminal Backup Power with Supercap Design FilesSmart Terminal Backup Power with Supercap User's Manual

Overview

This reference design has a wide input voltage range which supports 4.5V to 40V with 1A to 20A output. It uses a supercapacitor as a backup power supply and offers a solution for battery and electric double-layer capacitor (EDLC) based backup systems.

Supercapacitor Based Terminal Backup Power Supply Reference Design Board
  • The ISL81401 40V bidirectional 4-switch synchronous buck-boost controller can fully extract the power of a supercapacitor (can be as low as 0.3V).
  • Buck-boost with electric double layer capacitor (EDLC) backup with one ISL81401.
  • 100mA to 70mA options are available.
