Part Number: LP8555 Other Parts Discussed in Thread: LP5520 , LM3697 , LM3532 Dear TI technical support,
I contact you because I'm looking for a specific LED driver.
And after several hours of research, It seems that it is not so easy to find what…
Part Number: LP8555 What would the SW_B and FB_B pins be tied to if B bank was unused? Planning to not populate the inductor, diode and capacitors for powering Bank B.
Part Number: LP8555 Other Parts Discussed in Thread: TPS92360 , TPS61165 Hi,
LP8555 can connect two output A and output B together, provide total 12*40mA=480mA?
I have below 2+6 LED, but each channel need 60mA. But seems channel 1+ 3 + 5 total need 6*60mA…
Part Number: LP8555 Other Parts Discussed in Thread: LP5018 Hi Team,
TI have same NXP PCA9685 16 Chanel LED driver and I2C control?
PCA9685 16-channel, 12-bit PWM Fm+ I2C-bus LED controller (nxp.com)
Part Number: LP8555 The LP8555 datasheet recommends an inductance between 4,7uH and 6,3uH with 3,1A for most application. However in my application with L=4,7uH, i found a ratio between inductance peak to peak ripple current and mean inductance current…
Part Number: LP8555 Hi,
The datasheet that there is a soft-start function in LP8555 section 8.3.1.1.
What are the specifications about this soft-start function?
With an inductance 10uH I measure a peak inductance current during start-up at 1.5A and…
Part Number: LP8555 Hello,
According to LP8555 datasheet page 6, VOUT/VIN (MIN) = 1,3.
In my application at minimum current ILED=5 mA, i have :
VIN (MAX)=5,5V and VOUT(MIN)=Vf(LED) * Number of LED = 1,764*4 = 7,056V => VOUT/VIN =1,28 <1,3 .
I plan…
Part Number: LP8555 Other Parts Discussed in Thread: LP8557 , The Configuration of the Device we are designing contain 4 separate LED Drivers (LP8555*3, LP8557*1 all from TI). We need to Control all 4 LED Drivers from the same Control Chip through I2C interface…
Part Number: LP8555 Other Parts Discussed in Thread: LP8556
Hi I am trying to design the LP8556. I'm going to use the red LED (VF = 2V)
The current is about 10 mA to 20 mA per channel.
I want to control a total of 78ea LEDs with 13ea red LEDs per channel…
