Part Number: TPS61043 Hi,
I have noticed that the I_LED on the parametric search tool is incorrect at 50mA, while on the spec sheet it is at 60mA.
Thanks,
Alberto
Part Number: TPS61043 Can I use this to drive a single white LED?
The input voltage in the application will be approx 2V - 3V (two series AAA batteries).
To drive the LED, the output voltage will want to be ~3.5V (3.2V led Vf + 0.25V feedback voltage…

I've got a red-colored led like the LS M67K or similar.
My goal is to drive such led from a single CR2032 battery with a voltage variation from 3 volts at the start of the battery life to…
Other Parts Discussed in Thread: TPS61043 Hi,
My customer has question about TPS61043. Could you tell me about questoin?
[Question] - My customer considers to use TPS61043 for 2cell application. So my customer consider the design separating Vin from power…
Other Parts Discussed in Thread: TPS61043 Hello everybody,
I am working with the chip TPS61043 to control the backlight white LEDs of a LCD and I am observing a strange behavior. We want to use the pin CTRL to dim the lights. For design constraints the…
hi ameenu
We have limited backlight devices supporting input voltage low to 1.8V, only TPS61042, TPS61043, but have no I2C control. For input voltage higher, Lm36922, lm36274 can be options.
Other Parts Discussed in Thread: TPS61043 , TPS61042 Hi
What is responsible for the very different Vout ripple seen in Figures 13 & 14 of the d/s?
The operating conditions look similar in terms of LED current, pk SW voltage. The d/s doesn't have anything…
Other Parts Discussed in Thread: TPS61043 , TPS61042 Dear colleages,
I am currently working on a particular application where using 2 white LED as backlight, powered from 3V battery.
I am just wondering if TPS61043 is appropriate for this application…
Other Parts Discussed in Thread: TPS61042 , TPS61043 For TPS61042 and TPS61043 IC, I calculated the ripple voltage using the formula of the datasheet but it seems not correct :
10uF > 31mV calculated ; 110mV measured
1uF 300mV calculated > 680mV measured…
