TPS22811: Pulse output

Part Number: TPS22811
Other Parts Discussed in Thread: TPS61288

Hi support team,
I am thinking of connecting TPS22811 after TPS61288 as shown in the figure below.

TPS22811_square_wave.pdf

Input 12V, 4.15A.
Input 0.1515s pulse to EN.
At this time, is it possible to output 0V to 12V square wave with 0.1515s pulse?

Regards,
Dice-K

    Hi Dice-K,

    There is some delay with the device. Datasheet section 6.7 provides this delay. In case of dvdt open (fastest slew rate setting) and 12V, you get 0.63ms turn on delay. Similarly, you have some turn off delay of td,off + fall time (dependent on rc of circuits). 

    If you are fine with this much delay (especially if unequal delay for rise and fall) then the application should be fine. The device itself should be able to handle this application. 

    I apologies for delayed response. 

    Best Regards,
