1. A 0.1
碌F
low frequency ceramic bypass capacitor in parallel with a 0.01
碌F
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. Measured using a Wavecrest DTS2075 or equivalent.
