Product Details

The MAX866 evaluation kit (EV kit) is a fully assembled and tested surface-mount printed circuit board. It can also evaluate the adjustable-output MAX867.

The MAX866/MAX867 are CMOS, step-up, DC-DC switching regulators for small, low input voltage or battery-powered systems. The MAX866 accepts a positive input voltage between 0.8V and VOUT and converts it to a higher, pin-selectable output voltage of 3.3V or 5V. The MAX867 adjustable version accepts 0.8V to 6V input voltages and generates a higher, adjustable output voltage in the 2.7V to 6V range. Typical full-load efficiencies for the MAX866/MAX867 are greater than 80%.

A movable jumper on the EV kit selects either a 3.3V or 5.0V output voltage. Additional pads on the board's solder side accommodate resistors for the LBI/LBO low battery detector or MAX867 output adjustment.

Applications

  • 1-Cell Battery-Operated Equipment
  • Backup Supplies
  • Detectors
  • Pagers
  • Remote Controls
