TI中文支持网Hi TI
Regarding of TPS51220A specification page25 has a note “ if the user wants a further reduction of jitter, using the external clock synchronization provides adjustable phase shift between channels to avoid overlapping of switching events. See the PWM Frequency Control section.“
*this part only support 200kHz – 1MHz operation.
Is there any other way to improve the jitter issue? Can I change the frequency to 165Khz that jitter result is pass? it's whether it violates the guide?
Or, Does TI have a jitter limit that defines TPS51220A in various vin conditions?
Condition :Vin = 8vin & 13.5vin & 17vin
Fsw=332Khz
Vout=1.8
