APPEB1011 – Direct Solar Cell Charging


APPEB1011 is one of a set of evaluation boards designed to aid the development of energy harvesting applications with a CAP-XX supercapacitor, particularly with solar energy harvesting.

This board does not incorporate a maximum power point tracking (MPPT) switch mode power management IC (PMIC).  Instead the energy harvesting source is directly coupled to the supercapacitor and only a simple voltage limit circuit regulates the maximum voltage applied to the supercapacitor.

Main Features

  • PCB supports entire range of CAP-XX supercapacitors (Less than or equal to 100F)
  • Charge voltage regulation configurable via a jumper link with three max voltage settings; 2.5V, 2.7V and 3V
  • Output voltage control configurable via a jumper link
    • Direct connection between supercapacitor and the output
    • MCU controlled output with user programmable voltage thresholds to regulate duty cycle so supercapacitor is charged between load bursts.
  • Multiple test points
  • Test points for input voltage and supercapacitor voltage measurement
  • Includes 1Ω resistors for input and output current sensing

Note: The APPEB1011 Evaluation Board is made to order. Please allow 2-3 weeks for delivery. If there is a significant delay shipping your order, CAP-XX will notify you via email or telephone.
