PRODUCTION DATA.
The switching frequency is programmed from 50 kHz to 800 kHz by an external resistor (R7 in Figure 18). To determine the resistance by a given frequency, use the curve in Figure 4 or calculate the resistance value by Equation 1. Table 2 shows the recommended resistance values for some switching frequencies.
R7 (kΩ) | fSW (kHz) |
---|---|
800 | 50 |
400 | 100 |
200 | 200 |
100 | 400 |
80 | 500 |
