QUICK START GUIDE FOR DEMONSTRATION CIRCUIT 1409

probe tip directly across the VIN or VOUT and
GND terminals as shown in Figure 2.
1.
With power off, connect the input power supply
to Vin and GND.
2.
Check the Vcc Bias voltage-setting jumper JP5.
Move it into Vin position if required.
3.
Turn the input power source on and slowly in-
crease the input voltage. Be careful not to ex-
ceed 24V.
NOTE:
Make sure that the input voltage Vin
does not exceed 24V. If higher operating volt-
age is required, power components with higher
voltage ratings should be used.
4.
Set the input voltage to 6V and check for the
proper output voltage of 12V and 24V.
If there is no output, temporarily disconnect the
load to make sure that the load is not set too
high.
5.
Once the proper output voltage is established,
adjust the load and observe the output voltage
regulation, ripple voltage, efficiency and other
parameters.
