Other Parts Discussed in Thread: TPS92692
Hi, to whom it my concern.....
I intend to use TPS92692 for a Buck-Boost LED driver as suggested in the datasheet:
The application is a headlight for +12V and +24 vehicles. So the pecs ask for 9-36V for Vin (full range), I LED = 1A
The low bean will require 4 LEDs, totalizing 4 x 3,0 V typical totalyzing : 12V
But the high bean can be switched as well and the total number os LEDs in series will be : 8 LEDs, VLED=24V when high beab and low bean ON.
Looking when Vin=9V and VLED = 24V, LED+ will be equal to = 33V . The ratio between LED+/Vin = 3,6 , is it ok?
When Vin = 36V and VLED = 24V , LED+ will be equal to = 60V , the ratio LED+ / Vin = 1,6
Will this topology met the specs with no instability?
Thank you
