current is suppressed to 0. When the output is turned off by decreasing the S.C.P. terminal voltage below the lower
limit of the triangular wave (0.37 V typical) as shown in 3. 2), the consumption current does not decrease because the
IC is operating.
latch circuit of the IC is set so that the circuit fails to start. Adjust C7 or C8 so that the rise time for V
becomes 10 ms or longer.
Application Circuit Examples (contined)
Since the on/off circuit is not incorporated in this IC, it is required to add on/off circuit externally to provide a
