SWITCHING CHARACTERISTICS
SWITCHING WAVEFORM
APPLICATION DIRECTIONS
(1) Phase input
Phase input determines output mode:
(2) V
R
(reference voltage)
Stepless current level variation is available by continuously
changing V
R
.
(3) Current sensor
Compares voltage converted from amperage by current
sensing resistor to designated reference voltage level. When
they are the same, comparator triggers Mono-stable, and shuts
off output transistor during time frame t
OFF
. During this period,
current level decreases to slightly below reference level. When
period has passed, output transistor is reactivated. This series
of operations is repeated.
(4) Single-pulse generator
Mono-stable is triggered at comparator output phase rise edge.
Mono-stable output pulse width is determined by input to timing
terminals R
T
and C
T
, as follows:
t
OFF
= 0.69

C

If new trigger occurs during t
OFF
, it is ignored.
(5) Analog control
Stepless output current level variation is available by
continuously changing voltage V
R
or feedback voltage to
comparator.
