1. A 0.1 µF low frequency tantalum bypass capacitor in parallel with a 0.01 µF high frequency ceramic capacitor is recommended.
2. Figure 1 defines these parameters. Figure 2 illustrates the operating conditions.
3. Duty cycle is defined as (on time/period) per Figure 1.
4. Maxixmum control Voltage Leakage Current is by design.
