Part Number: LP8868X-Q1
Dear Sir/Madam,
I am currently using the LP8868-Q1 LED driver IC in a buck-boost topology to drive 5 LEDs under the following operating conditions:
Input Voltage Range : 9 V to 16 V (Typical: 13.5 V)
LED Forward Voltage…
Part Number: LP8868X-Q1 Tool/software: Input voltage =13.5
output current =2.1A
can you please calculate power dissipation of Led driver IC and other component @25degree,65 degree
Part Number: LP8868X-Q1 Tool/software: Dear Sir,
I hope you're doing well.
I would like to confirm whether the LP8868-X, configured in boost topology, is capable of handling a load of 46 watts consisting of 12 LEDs, each with a forward voltage of…
Part Number: LP8868X-Q1 Hi,
i see this LP8868X-Q1 device is new, so parts not available. i have an application with the following spec, buck boost topology..
input voltage 5v - 7.2v, varying, as its derived from an excellent TI battery charger part…
Part Number: LP8868X-Q1 Tool/software: Hello,
Not sure if this is the right form or not.
I am working on a boost circuit for a personal project using the LP8868, I keep running into an issue with the circuit not working. I think I may have calculated…
Part Number: LP8868X-Q1 Tool/software: Dear TI experts,
My customer made a sample module using LP8868XQDMTR-Q1.
Could you review the schematic below first?
And here is a question ;
If the VIn is normal(usually 13.5V), everything is okay but…
Part Number: LP8868X-Q1 Tool/software: HI,
Attached is my design.
Issue is when i increase PWM the inductor ripple increases, and the input voltage drops below 4.6V.
Using in PWM Mode
Am suspecting
1. RCOMP,COMP,RDAMP Values
2…
Part Number: LP8868X-Q1 Tool/software: I'm looking to use LP886X-Q1 to control multiple LEDs and am not sure how to find R_LED to be able to calculate other external component values.
It's deltaVf/deltaIf, but I don't know if deltaVf is the voltage…
Part Number: LP8868X-Q1 I am working on a project in which the LP8868X-Q1 is being used. Currently I am trying to simulate the circuit which includes this part, however in the PSpiceTI part library it does not seem to exist. Has the part not been added…
