TPS272C45: TPS272C45

Part Number: TPS272C45

Tool/software:

Hi 

The data sheet for the TPS272C45 states the maximum pwm frequency is 1khz, however Figure 7-12 show a pulse of 200e-6 sec. I am interested in the maximum pulse train, i.e. 50% duty cycle. 

Thank you 

John

    Hello,

    The maximum PWM frequency stated in the switching characteristics is 1 kHz, which is equivalent to 500 Hz at 50% duty cycle. The figure in 7-12 is connected to the SNS characteristics which are much faster. They are outlined in Section 7.6. 

    Best Regards,
