Electrical Characteristics
(VCCA = 5V, VCCP = 12V, TA = 25
°C using circuit of Figure 1, unless otherwise noted)
The denotes specications which apply over the full ambient operating temperature range.
Notes:
1. Total DC accuracy includes setpoint accuracy, temperature drift, line and load regulation.
2. The on-time pulse width of the oscillator is set via external capacitor CEXT.
