Part Number: TPS61193
Hi,
I'm looking for a LED driver to drive the backlight of a TFT display.
At the moment my reference pn is MAX16814BEUP +, I would like to know if there is an alternative TI.
Here are the features:
- I have to drive 3 channels in parallel with Vout_max = 27V (3 chains of 7 white LEDs each)
- each channel must be able to generate at least 85mA (3 x 85mA or 1 x 255mA)
- the input voltage can be + 33V (in this case we have to choose a buck - NO LINEAR) or + 5V (in this case we have to choose a boost)
- I must be able to control the output current in PWM, without having to differentiate the duty cycle between the channels
At the moment I was looking at TPS61193, but maybe you can offer me some other options?
Price is fundamental, target 0.7 $ for 1000pcs / yr.
Many Thanks,
Antonio
