Driving high current LEDs that are being pulsed for optical data operation from a battery
I have an application where I am driving 4 LEDs in series.I am driving with 1A with a forward voltage of 2.5V per LED.This is easy to accomplish using a 15V supply.
But for this applicationI only have a 3.7V lithium battery as the source to drive them.The LEDs are used for optical communications and are pulsedat 1MHz to generate the binary data output.
Is there a TI part that I can use to generate the necessaryvoltage (12-13V) and current (1A) to operate the LEDs for this type of application?
have a look at TPS61087 and/or at TPS61500,
in according to the side specifications you have to meet
