Part Number: TPS75105 Other Parts Discussed in Thread: TPS75100 , LP5562 , Hello. We presently use the TPS75105DSKT, or WSON package, in our products. My search does not show this part is available as WSON - only BGA. We cannot use the BGA. Is there pin…
Part Number: TPS75105 Hi Sir,
I can find Over current and Over temperature Protection features in TPS75105 datasheet.
Can you have more detail about these features?
Thanks.
My customer would like to know if the LED driver TPS75105DSK will work with 1.8V control for the two enables Right now I they are driving it with 3.3V I/Os but are running short on 1.8V GPIOs and I need to remap those GPIOs from a 3.3V to a 1.8V bank…
Other Parts Discussed in Thread: TPS75105 What does the output impedance of the TPS75105 LED driver look like?
Does it change significantly from ENx=low to ENx=high?
HI Bob,
I am not aware of an easy way to do this externally. You are already getting 1.4% accuracy, which is well within the tolerance of the system if you are using a 1% resistors and a 1.5% LDO.
You could try another part the TPS75105 this is…
Hi Anand,
I am not sure I fully understand what it is that you are attempting to do. It sounds like you are looking for a current regulator. Please take a look at TPS75105 and see if this will work in your application. You are able to set the current…
Hi RR,
Take a look at TPS386000 and TPS386596L33. These are both quad SVS devices that you can set the rail to be monitored via external resistors. Both devices have /MR pins. Both devices are available in surface mount packages and can be run off a…
Beside the approach listed in the app note, the following devices might be from interest due to the simlicity of their use.
Depending on the LED forward voltage a "step-down" or "step-up" type of LED driver is needed. Both should contain internal current…
I couldn't see any exact pin2pin part, but similar (in functionality)...
have a look at the http://www.ti.com/product/tps75105 and http://www.ti.com/product/tl4242
