TPS82130: About switching frequency and built-in inductor

munakata akio
Prodigy 10 points
Part Number: TPS82130

Please tell me the MIN value and MAX value of PWM switching frequency under the conditions of Vin = 12V, IOUT = 1A, VOUT = 1.8V.

The inductor value is 1uH.

Please tell me the min value and MAX value.

    Hi Munakata,

    Please refer to TPS82130 datasheet, The typical switching frequency is 2MHz in CCM mode. The switching frequency in power save mode is estimated as equation 3. The switching frequency range for 12Vin, 1.8Vout and 1A is in Figure 21.

    Thank,

    Nancy
