5. Make sure the jumper (J61) is in the internal feedback posi-
tion (default 1-2)
6. Turn on the control supply – make sure the supply is between
7 V and 12 V range (8.5 V is recommended).
7. Turn on the main supply voltage to the required value (do
not exceed the absolute maximum voltage of 24 V on V
To ensure that the circuit starts, it is recommended to start at
8 V and increase or decrease to the desired value.
8. If the unit does not self-start in step 7, then press the start
button and hold for at least 2 seconds. Observe that the sys-
tem operates on its own once the button has been released.
Pressing the start button will connect the internal oscillator
to the feedback circuit to help establish the currents and
voltages in the system to function on its own upon release
of the start button. The internal oscillator is set to 7.372 MHz
(well above the operating point) and it may be necessary to
increase the voltage or reduce the load to start the circuit.
9. Once operational, adjust the main supply voltage and load
within the operating range and observe the output switch-
ing behavior, e ciency and other parameters.
10. For shutdown, please follow steps in the reverse order. Start
by reducing the main supply voltage to 0 V followed by steps
6 through 2.
