Please let me know the minimum,maximum value of the switching characteristic of TPS22949D.

It is only typical value at the datasheet..

Hi,

The switching characteristics for the TPS22929D are only specified at typ because they will change depending on voltage, temp and load. Effects of these conditions are shown in the graphs in datasheet section 7.7.1 Typical AC Characteristics.

Hi, Adam.

There is only a graph of temperature and voltage dependency in the datasheet.

I want to know process variation in a certain condition.

Do you have any data?

Hi,

Can you tell me what is your input voltage and which AC parameter you are interested in.

I can then provide some simulation data showing min/max for your use case.

Regards,

Adam

Hi, Adam.

Input voltage is 1.5V and 3.3V.

I'd like to know all ac parameters.(Ton,Toff,Tr,Tf)

Hi,

Here are the simulation results for these conditions:

VIN = 1.5V, RL=10ohm, CL=0.1µF (Full Temp)

PARAMETER	MIN	MAX	UNIT
tON	5596	26635	µS
tOFF	18.29	19.35	µS
tR	14024	33289	µS
tF	17.64	18.46	µS

VIN = 3.3V, RL=10ohm, CL=0.1µF (Full Temp)

PARAMETER	MIN	MAX	UNIT
tON	3580	10966	µS
tOFF	7.67	13.03	µS
tR	3700	8266	µS
tF	2.91	5.18	µS
