Part Number: TPS2640 Other Parts Discussed in Thread: TPS2660 , SN74LVC1G14 Hi Team,
Can you suggest most simple power mux with TPS2640 ( there is no need for fast switchover time). ( eg FLT and SHDN pin)
Input 1 ( Always has priority)
Vin1 from 12V…
Part Number: TPS2640 Hi Team,
we don't use RPP on TPS2640, is it ok to connect RTN to GND ?
also by doing this ( connecting RTN to GND) is any other functionality besides RPP disabled?
Br,
d.
Part Number: TPS2640 Hi,
According to the datasheet P.10, Output ramp time is typical 8.35ms as follows:
However, we calculate the tdvdt (Output ramp time) on Equation2 on the datasheet P.18.
Result is tdvdt = 20.8 * 10^3 * 24V * 80% * 22nF = 8.785ms…
Part Number: TPS2640 Hi,
I have two different boards with the same circuit using the TPS26400RHFR. The same schematic but different layout.
The first one, with the SHDN pin floating, Vout starts correctly when Vin is ok. However, the second one doesn´t…
Part Number: TPS2640 Hi,
I have two questions.
*1. According to the TPS2640 datasheet P.14, we can find the Figure7-25 Graph of "Thermal Shutdown time vs Power Dissipation". On this Figure7-25, could you please let us know the board configuration…
Part Number: TPS2640 The datasheet lists 250[us] as typical for SHDN exit delay, but an application I'm supporting may need to toggle the output on/off repeatedly. I need to know the max time for SHDN exit delay. We can use the C(dvdt) = Open setting…
Part Number: TPS2640 Hi,
My customer only supplies 24V on OUT pin of TPS2640 under system test condition. Other pins (including IN pin) are no power supply as follows. On this case, what is occurred? Is TPS2640 is damaged? Please advise us.
I hope "Capacitor…
