Electrical Characteristics (Continued)
(VCC = 18V, FOSC = 135kHz, TA = 25°C, unless otherwise specified)
Note :
1. These parameters, although guaranteed, are not 100% tested in production.
2. Recommend operating condition :
- Vcc(min) = 12V
-RT = 3.3kΩ ~ 10kΩ
- Oscillation frequency = 5kHz ~ 600kHz
- Soft start capacitor(CS) = 0.1uF ~ 1uF
