Other Parts Discussed in Thread: TPS92515, TPS92518, TPS92515HV,
We need to control a string of LED for fast flashes that might be a few seconds apart.
We have started to look at the TPS92518 as well as TPS92515.
The main parameters are :
DEL Strip curent = 1 A
DEL Strip Voltage = 40 V
Time ON = 1 us to 4 ms
Time OFF = 500 ms to 10 seconds.
We will control the ON / OFF time of the pulses with an external signal.
We might want to use Shunt Fet Dimming for the fastest way to have short current pulses.
Is the TPS92518HV a good part selection ? Or the TPS92515HV ?
Is there any potential problems or important design issues with the fact that there is a long OFF Time for the DEL Strip ?
We want a minimal power cunsumption.
