Part Number: TPS22968-Q1

Hi team,

I would like to know tD, tr, tf parameter (typ/min/max) in the datasheet at the following condition.

1. VIN=VON=VBIAS=3.3V, CT=470pF

2. VIN=1.8V, VON=VBIAS=3.3V, CT=470pF

Could you advise the value?

regards,

Hi Shinji Tsuji,

Unfortunately, we cannot provide any testing parameters for tf for CT values less than what is stated in the datasheet. Due to the quick output discharge nature of the part, there is no difference on the falling time over different CT capacitance. Similarly, as long as Von>Vih, the effect of different Von is not significant to the timing. All timing below is in us.

1. At VIN=VBIAS=3.3V, CT=470pF

Parameter	min	typ	max
t_r	714.59	779.77	865.29
t_d	292	351.56	426.5

2. At VIN=1.8V, VBIAS=3.3V, CT=470pF

Parameter	min	typ	max
t_r	413.81	449.51	495.38
t_d	264.5	324.75	404

Thanks you for choosing TI Power Switches in your designs.
