APPLICATION DESCRIPTION
Test circuit
Switching waveforms
PHASE INPUT
Phase input decides the output mode.
Current sensor
When the voltage fall at the current sensing resistor and the
selected current level becomes of the same level, the comparator
triggers the monostable. Then, the output stage is cut off for a
certain time (t
OFF
). During this cutoff time, the current volume
decreases slightly and falls short of the comparison level.
After the cutoff time (t
OFF
), the output stage is in ON state again.
This operation is repeated.
Single pulse generator
At the comparator output rise edge, the monostable is triggered.
The pulse width of the monostable at the external timing R
t
and
C
t
is as follows.
t
OFF
= 0.69 x R
t

Retrigger during t

is neglected.
Analog control
The output current level can be continuously changed by
changing the voltage at V
R
or the feedback voltage to the
comparator.
