Synchronous PWM Controller
AP2014/A
Electrical Characteristics
Unless otherwise specified, these specifications apply over VCC=5V, VC=12V and TA=0 to 70°C. Typical values refer to TA =25°C. Low duty
cycle pulse testing is used which keeps junction and case temperatures equal to the ambient temperature.
