PRODUCTION DATA.
Inductance for both inductors can be selected from Table 54, depending on operating frequency for the application. Current rating is recommended to be at least 25% higher than maximum inductor peak current. Peak-to-peak ripple current can be estimated to be approximately 40% of the maximum input current and and inductor peak current can be calculated with Equation 15, Equation 16, and Equation 17:
SW FREQUENCY (kHz) | INDUCTANCE (µH) |
---|---|
300 | 15 |
400 | 15 |
600 | 10 |
800 | 10 |
1000 | 6.8 |
1250 | 6.8 |
1667 | 4.7 |
2200 | 4.7 |
