Description
Output pin
GND
Input pin
Outputs an intermittent source current at a duty proportional to an input voltage
GND
Applies a control voltage.
Connect a capacitor to eliminator a noise.
Output a triangular wave, which serves as a reference for the PWM signal,
to the Pin6 by connecting the resistor R
T
between the Pins5 and6, and
capacity C
T
between the Pin6 and GND.
Output a triangular wave, which serves as a reference for the PWM signal,
to this pin by connecting the resistor R
T
between the Pins6 and 5, and
capasity C
T
between the Pin6 and GND.
Noise eliminating capacity connection pin 1
7
Noise eliminating capacity connection pin 2
Connect a capacitor to eliminator a noise.
