Switching frequency

Category: Datasheet/Specs
Product Number: LTM8056

In datasheet, table 3 is given for switching frequency and RT for selecting RT and in the application model circuit, they have chosen intermediate frequency and RT values. How to choose the my switching frequency based on my input and output voltages, any formulas for RT, FSW?

Input Voltage range: 16-36V

Output Voltage: 28V

Output Current: 1A

Edit Notes

  • Hello Gow,

    In table 1 of the datasheet, values for Rt and Fsw are suggested for various Vout conditions. These designs were optimized on the bench at these frequencies to show the best efficiency. For 28Vout, 500kHz-525kHz is recommended.

    Regards,

    Wesley
