_________________EV Kit Information
The MAX786 evaluation kit (EV kit) embodies the
standard application circuit, with some extra pull-
up and pull-down resistors needed to set default logic
signal levels. The board comes configured to accept
battery input voltages between 6.5V and 30V, and pro-
vides up to 25W of output power. All functions are con-
trolled by standard CMOS/TTL logic levels or DIP
switches. The kit can be reconfigured for lower battery
voltages by setting the oscillator to 200kHz and
increasing the 5V output filter capacitor value.
The D1 and D2 comparators can be used as precision
voltage detectors by installing resistor dividers at each
input.
