I'm disty in Japan.
I'd like to ask you about the switching frequency of TPS62130A-Q1.
My customer is considering using TPS62130A-Q1 to next model.
He likes TPS62130A-Q1 with high efficiency characteristic (specially, in the power save mode) very much.
He would like to know the switching frequency of this device.
The switching frequency must maintain over 1.8MHz in his application,
because the clock noise of under 1.8MHz influence other equipment.
Can the switching frequency of this device maintain over 1.8MHz
in consideration of temperature characteristics and process variance
under the following conditions?
1)Vin= 5V, Vout=3.3V,Iout=3A
2)Vin= 5V, Vout=1.5V,Iout=3A
*We are concerned that the switching frequency suddenly drops
at input voltage below 6V.
Additional information, he knows that TPS62090-Q1 may be better than TPS62130A-Q1
under conditions of above only.
However he is considering TPS62130A-Q1 preferentially to have possibilities
to be usable in not only next model but also other models,
because it has the characteristic of wide input voltage range.
Best regards.
