3. Application circuit using diode at reference terminal
TA7630P
The application circuit using diode between Pin 5 and Pin 12 has the following merits. (1) When each control terminal is drived by high impedance, the electrolytic capacitor between terminal
5 and GND operates as the back up capacitor, so that the rise time is short at the ON-OFF repetation of supply voltage.
(2) When the current drain into the each control terminal varies by control voltage, the voltage of
terminal 5 scarcely varies. It means a stable reference voltage.
